SUBJECT USSR/MATHEMATICS/Differential equations CARD 1/1 PG - 65 AUTHOR XONONZNKO V.0. TITLE _~'n -the os6-illa-tions of non-linear systems with many degrees of freedom. PERIODICAL Doklady kkad. Nauk 105. 664-667 (1955) reviewed 6/1956 A method is given for determining periodic solutions of a system of differential equations of n degrees of freedom.the coefficients of which are slowly varying almost periodic functions and the non-linear parts of which are multiplicated with a small parameter C...The method is applicable if the stationary oscillat- ions possible in the system essentially take place with one frequency. 'Oter the transformation of the starting system which corresponds to a principle- axes-transformation of the linear partial system, the solution is set up in the form of an asymptotic series in terms of powers of E. Corresponding series are found for the slowly varying phases and amplitudes of the wanted solution. The coefficients of'the series expansions are given ias trigonometric double series. If these are determined, then the problem is reduced to the integration of the defining equations for phase and amplitude, a problem which can be reduced to simple quadratures if amplitude and phase occur in separable form. Slightly non-linear systems with purely periodic coefficients are con- tained as a special case in the considered starting system and give certain simplifications of the method of solution.

'Izvestiya Akademii nauk SSSRI, Otdeleniye tekhnichesk1kh nauk, 1958, Nr 6, pp, 87 - 90 (USSR) ABSTRACT: Transverse vibrations of a rotating shaft carrying a disc are considered. These vibrations occur when the system is not balanced. The.system under consideration is illustrated in Figure 1 and the equations describing its motion are given by Ecp(l). In these equations m is the mass of the discq I is its moment- of inertia, o is the rigidity of the shaft and 0 is the off-ceittre distance. The system of equationt is non-linear and an approximate method Of solution (Ref 2) is used. It is assumed that the vibr- ations do not differ very much from harmonic vibrations and that the angular velocity changes very slowly. In that case all the,terms on the right hand side of Eqs(l) can be looked upon as small. Using the substitutions given by Eqs (2), the s7stem. of Eqs (3) is obtained in which e is a small parameter. The solution is given by Eqs (6) and Card 1/2 SOV/24-58-7-13/36 Resonance Vibrationa of-a Rotating Shaft Carrying a Disc An erpres3ion for L is given by Eq (8).

The investigated oscillatory systems occur in the motions of mechanisms of instruments i-iorking on a vibrating base (Ref 1) and in problems of the mot-ions of charged particles in accelerators (Refs 2 and 3). The fundamental differential equation discussed is: d2x/dt2 + (b0 + b 1 Cos wt + c Cos-Vt) x = 0 in which the frequencies w and V may be incommensurable, the positive coefficients b 0 and b, can take any values and the coefficient c is assumed small in Card 1/3 comparison with b 0 and b1, This eauation is solved On Parametric Resonance of Fractional Order SOV/24-58-8-10/37 with the aid of Mathieu functions, and only those motions ?f the system are considered for which the frequency X1 is near to a where + ia are the characteristic indices associated witF the Mathieu functions. For a =.a and also for values of A near to a the motions are unstable and the corresponding states of -the system are resonance states. Resistive forces (friction) have a considerable influence on processes characterised by parametric resonance of fractional order. The solution of the equation d2x dx = + k at + (b0 + b, cos 60t + c cos Vt) x = 0 (21), dt in which the second term is considered a small frictional term proportional to the velocity can be obtained by the same method as that for Eq.l. It is found that the friction reduces the area of partunetric resonance.

To find its solution and in order to minimise the values of its right term, the following assumptions are made: the vibrations are harmonic, the angular velocity * does not (P exceed the period, the frequency w 5 of the specific vib- ration of the system is the root of its characteristic equs~t- ion, and the value *k w (k -- 2, 3,...) does not apply. The system (1) can be represented as a collection of indep- endent vibrators, each satisfying the Eq (2). Then, from Eqs (1) and (2), the expression (3) can be derived, where the function 2 B is defined as Eq (4). If w S is the specific frequency of the system, then Eq (5) can be defined, the solution of which can be expressed as Eq (6). from which the stationary vibration in the resonance region is obtained as Eqs (7), (8) and (9). The solution of the problem can*be expressed in the general form as Eq (10). As rl and a can have several solutions, only those are chosen which correspond to a stationary condition of the system. These are expressed as Eqs (11), (12) and (13), from whir--h the Card 2/4 Eq (13). written in the form of Eq (14), is the most signi- 30,i/179-c9-2-11/40 On Resonant 11r'ocesses in the Vibrating System Containing a L-Iotor ficant.

The calculations show that the charaoter of the resonance depends on the properties of the mo`56r and on the reser-,e of power of the motor , A part of the latter can transform into the resonan-.e which can be satisfied by the velocity SI and frequency a. as illustrated in Fig 4., where the graphs Card 3/4 SOV/1'79-591-2-11/40 On Resonant Processes in the Vibrating Syster.

The slab carries a motor, whose shaft has an unbalanced mass and so produces unbalanced forces when rotating. The rotor of the motor has a moment of inertia, a driving torque and a load torque, both of which are functions of the shaft speed. The slab motion against its spring constraint is assumed one-dimensional. The driving torque, load torque and damping function of the linear motion, are assumed known. The unbalance mass is-assumed small, compared with the slab mass and the difference between the driving and load torquesis assumed small. The equation of motion of this Card 1/4 88519 S/179/60/000/006/011/036 E191/E135 Forced Oscillations of a System Containing a Source of Energy in the Presence of a Small Non-Linearlty system is formulated. It is assumed that the oscillations will be near harmonic and the angular velocity of the motor shaft will vary slowly compared with the period of oscillation. In the sense that the system is mechanically self-contained, its oscillations can be thought of as self-excited but the designation "forced oscillations" is used to signify the similarity of systems which are examined without consideration of the properties of the source of energy. The solutions of the problem are stated (Eq. 2). The angle of shaft rotation and the linear displacement of the slab as well as its linear velocity are defined in terms of a basic uniform rotation for the shaft and a basic harmonic oscillation for the slab on which are superimposed additional small periodic functions. Asymptotic methods of solutions are used to determine the parameters (angular velocity, amplitudes) of the basic motions. Under steady state conditions the angular velocity of shaft rotation is constant as is the amplitude of slab motions This motion is sinusoidal with Card 2/4 88519 S/179/60/000/006/012/036 2191/E135 Forced Oscillations of a,System Containing a Source of Energy in the Presence of a Small Non-Linearity a period exceeding that of the shaft rotation by a constant &mounte The angular velocity of the shaft is not arbitrary but several solutions exist determined by the properties of the motor. The steady state solutions are examined for stability by the metho4n of I.G. Malkin (Ref.12). It is shown that by changing the nature of the torque as a function of the speed of the motor it is possible to change stable into unstable states and vice versa. An example is given wherein the non-linear term in the spring characteristic is a cubic terms The motion of such a system has been studied in detail when the frequency of the exciting force is a given constant. In the present system, two cases of non- linearity are considered, namely a stiffening spring and a relaxing spring (cubic term positive or negative, respectively). The differences between the present case and the well known resonance curve of a non-linear system are discussed. The discontinuous changeover between two states depends on the Card 3/4 88519 S/179/60/000/006/011/036 El9JL/E135 Forced Oscillations of a System Containing a Source of Energy in the Presence of a Small Non-Linearity characteristics of the surplus torque as a function of the motor speed. In the case of a relaxing spring, when the surplus torque decreases with increasing motor speed, the unstable condition may be transferred from the rising branch of the resonance curve to its falling branch. The difference between the stability of the system at a prescribed motor speed and a system with a self- adjusting motor speed is discussed. A system unstable at a set speed can become stable. The superimposed periodic deviations from the basic motions are shown to be small for the system considered. There are 4 figures and 13 references: 12 Soviet and 1 English.

AN SSSR, OTN, Mekhanika i mashinostroyeniye, no'.5, 1960) wherein steady-state conditions were examined subject to limitations determined by the approximate methods of analysis employed. In the present paper, a parametric oscillating system with a low depth of parameter modulation is considered on the. assumption that the source of energy which imposes the periodic (or almost periodic) variation of the parameter of the system can interact with the oscillating system so that the oscillations become dependent-on the properties of the energy sourcei The physical oscillating system considered is an elastic bar subject to a periodic force in its axial direction, so that its bending Card l/ 3 S/179/62/000/003/006/01.5 On the resonance properties E191/E413 stiffness changes periodically. Under certain conditions, as a result of the periodic variations of stiffness, parametric oscillations of the bar in the direction transverse to its axis take place. Details of the system are given in Ref.l. The - equations of motion are formulated, and its simulation by an analogue computer is illustrated with the help of a block diagram and discussed. The equations of motion contain a term with the cubed transverse coordinate. The coefficient of this term is the nonlinearity parameter which, in the present paper, is examined within a wider range than before. The purposes of the simulator studies were (a) to establish the motion of the system under steady-state conditions at positive, negative and zero values of nonlinearity; (b) to clarify the nature of the nonstationary conditions of motion arising near the boundaries of stability and corresponding to the transition from one steady state to another dhd (6) tb 6boOrve the motion of the system when the conditions of stability are not fulfilled.

The results of the analogue computer simulation are illustrated and discussed, selecting the behaviour in -the resonance region where the interaction of the oscillating-- system with the source of energy is most pronounced. The three cases of hard, soft and zero-restoring force arc considered separately. The main result of the present investigation is a. broader view of the nonlinearity parameter limiting the amplitude of parametric oscillations. In systems considered here, the factor which limits the amplitude of pArametric ospillations is the nonlinear link between the energy source and the oscillating system, This-link,varles with the variation of the steepness of the cLracteriatic curve of the energy source, so that parametric oscillations with*limited amplitudes can'be obtained by an appropriate variation in the steepness of the energy source curve. ~There are 11 figures.

At the same time also the extent of the deformation of the sample can be determined. An automatic recording of the data is made by the apparatus. As may be Peen from a diagram given the apparatus consists of three mair. parts: the loading device, the electrical indicator for the deformation measurement, and a small stage for fixing the sample. From a diagram of the deformation of a rook sample as a function of the load it may be seen that in spite of a step-wise displacement of the drum the recording is sufficiently accurate. The apparatus described may also be used for testing other non-metallic materials (rubber, ebonita, plastics etc.). Card 1/2 There are 2 figures.

MW TITLE: On Normal Waves With Flexural Vibrations of a,Plate PERIODICAL; Akusticheskiy zhurnalg 19609 vol. 6, No. 1, PP- 57 - 64 TEXT: The present paper deals with'.the investigation of the propagation of flexural vibrations along an infinite elastic band with aidth K and thickness h. The following cases are dealt with: the plate margins are free, fixed, and with articulate support. Gorresponding dispersion equa- tions are derived and solved (Figs. I - 6). In completion of theoretical considerations, experiments were made on a 160 cm long aluminum- band. 2 The parameters of the band were: ?-= 2.65 g/cm3, E = 705 - 1011 dyn/cm a-= 113, h = 0-3 cm, H = 5 cm. Q - thickness of the material)* The method described by N. S. Ageyeva in Ref. 1 was applied. The excitation of the band vibrations was made with the aid of a piezoelectric vibrator with a frequency of 12 kc/sec. With an asymmetrical excitation the author obtained the wave form of Fig- 7, and with a symmetrical one, the Card 113 On- -Normal Waves With Flexural Vibrations S/046/60/006/01/09/033 of a Plate B008/BO11 wave form shown in Fig, 8. The normal zero wave was not established, as the conditions for its excitation were unfavorable. Figs- 7 and 8 also indicate the measurement results showing the distribution of the dis- placement over the width of the plate. The coordinate x is plotted on the vertical axis, and the amplitude of the displacement on the hori- zontal one. The table contains.the distances between the nodes for dif- ferent y-values (symmetrical excitation), and the calculated mean value of-5-37 cm. The same distance determined theoretically is 5.4 cm. Thus it was possible to establiab a good agreement between theory and experi-lzc ment. The ocdamnce of waves of other orders of magnitude, which are in- evitable under real condLtiona, was found to be the cause of a certain dIvergence-This circumstance gave rise to a distortion of the node lines.(Table). The occutrence of a.tranaversal resonance was observed, as expected, on the frequency with a critical value for the wave shown in Fig- 7. The wave did not'propagate under this frequency and entered the class of inhomogeneous waves. The author thanks N. S. Ageyeva for Card 2/3 (KOVENKOV Yu 2 RVK-A- W20igh-tYps f:Lwmral wave.

In principle the scheme consists of four coils, two selenium rectifiers and two relays which form part of a common circuit, which, by the rising or falling motion of an iron core (which isenolosed in a glass ampule and generates induction Gar- rent) opens and closes an electromagnetic three-way faucet. The latter is mounted on the container of the liquid, Which, besides, is connected with the vacuum as well as with the spare container for the liquid and with the filter. By the interaction between the vaaaum and the three-way faucet connected with the atmosphere, which is connected with the level of the liquid (by a float), the container is alvmys filled up again as soon as the level is reduced Card 1/2 to a certain height, so that in this my a continuous feeding of The Automation of the Filtering Process of 32-3-49/52 Injection Solutions the filter is attained.
