TITLFt Characteristics of steel rupture under cyclic loads In connection with the anisotropy or Its structure PERIODICAL: Referativnyy zhurnal, Hatallurglyao no. 11, 1962, 46, abstract 111290 (In collectIons "Taiklich. prochnost' metallov",'Moscow, AN SWH,o 1962s 94 - 109) TFITt Various kinds of mechsnical testa (torsion and tension of a "lamt-._ nated" sample) are considered from the viewpoint of their suitability for eva- luating the tendency to cleavage of a wide row of products and materials or An- Isotropic structure. The investigations were carried out on special "laminated" samples prepared or sheet material 12 m thick [ 14 r2. 15 re (M2, i5m) steels] and of a rod 25 mm In diameter [ CT 3 (3t.3)). Torsion tests were carried out on a crankshaft-type fatigue machine (loading frequency - 1,400 cycle/mIn,) . It'' is p9inted out that cyclic torsion in a more sensitive method or revealing the tendency to cleavage than static torsion. Under conditions of cyclic torsion, Card 1/2 r,,/137/62/OCO/011/024/045 Characteristics of steel rupture under... A052/A101 the characteristics or the cycle (alternation, assymetry) are not so Important as Its loading rrequoncy to produce a cleavage-type fracture. To investigate the tentlency to cleavage at tension a new "laminated" type or a m-nple (the cut- ting scheme and the form of the sample are given) Is proposed. The mentioned samples were tested under asymmetric one-sign cycle on a modernized Inertia-type" machine; loading frequency a 3,000 cycle/min. The cleavage te.,t reveals a now property of an aninotrople material which cannot be detected by the usual method of anisotropy evaluation by comparing properties of longitudinal and lateral samples. The results or an investigation of rod steel have shown that all lawsO established for sheet steel, hold true for It; the rolling resistance In the direction perpendicular to the planes of cleavage Is lower than in any direction along these planes. Photos or fractures are presented or the samples with a dif- rerent orientation In relation to the direction or rolling, and characteristics of cyclic rupture of sheet and rod steel discovered In the process of fatigue tests of "laminated" samples are discussed.

To transmit radar signals to the moon vIth pulses on the order of 2,o- see in the centimeter bwAit is necessary to bive a "a poveron the order of 1-2 megawatts. It is therefore advisable to use the phase method which requires loss Wwo Owing to tbA complicated character of the reflection of centimeter radio vaves from the log n, It is necessary to employ not the direct phase netbod, but a modification of the metbod, by vhich the radio signal is madulate& with a low frequency'and the pWse differ- ence betvm the nodulation ft*quency of the slgml reflected from the moca and of the direct signal is measured. Me modulation frequency'is determined by the filmm Ions of the reflecting area an the moono vMcb depends In turn cc the vidth of the directivity pattern of the antenns, empUrd. Utimstes wds for a 16-qeter antenne. at a 400 cycle modulation frequency show that the measurement accuracy reaches 1#2 ka at a pmmr of 2000 watts. Card I Y3SR / Radio Ph.-r-jloz.

By way of compa~rison he also deals with specialized and copying machines. He says that the ever-incj~eaqibg automation in production (at, Avtomaticheskiy zavod porshney (Automatic Piston Plant), which was put into operation in 1950, produces more than 2 million pistons per year; the Pervyy podshipnikovyy zavod (First Bearin&Plant) in Moscow has an annual output of more than Card 1/4 1 million-bearings) as well as the continually Program-Controlled Machines SOV/25-59-2-5/48 changing requirements in the fields of avia- tion, electronlca~ radio engineering, etce account for the growing importance of pro- gram-controlled machines, which combine the general quality of mass-producing machines 'with the individual advantage of a possible swift and thorough change in the production program. The program-controlled machines surpass the copying machines,, whose 'models are rather time-consuming and expensive, The block-system type machine, as exhibited by the authorg consists of four assemblies or units and the body of the machine. The pro- gram unitis an installation, by means of which the program carrier is put into opera- tion. In recent Soviet models the program is recorded on a magnetic tape in the form of separate magnetized sections (ohtrikhi - facsimile records). The 11readin6" of the pro- gram signals and their transformation into Card 2/4 electric impulses is performed by magnetic Program-Controlled Machines Card 3/4 SOV/25-59-2-5/48 heads (golovki), which direct the impulses to the control unit, the functions of which are extremely complicated and consist-mainly in the deciphering of the impulses and their adequate transforming -to control the power sources and the implementinc mechanisms of the machine# The latter aonstttq%pthA third unit. An "active control",, based on a feedback aystem, is exercised by the fourth unit. The basic element of this unit is a "feeler", with the aid of which the measure- ments of the work piece are determined during the machining process. If the machined piece itself cannot be measured, then the angles of rotation or displacement of the machine parts9 on the precision of whose movement the quali- ty of the machining procoss depends, will be determined.. Such parts are, for instance, the tables of jig boring and milling machines. The results 01 the measurements of the active control urit are transformed into electrical Program-Controlled Machines SOV/25-59-2-5/48 signals, which are directed to the already mentioned control unit (second -unit). This units therefore, has to accomplish a double function, -ghich on the one hand consists in the accomplishment of the above-mentioned task and on the other hand in the reception and processing of the signals from the active control unat. These two functions are per- formed simultaneously, so as to utilize im- mediately the corrections of the active con- trol unit in the directions given to the imple- monting mechanisms and to reduce the errors of the machining process to a minimum.

Nr 48, and RZhMekh, 1954, abstract 3979) on the subject of the study of -mechanisms with elastic. connections operating under conditions i. corresponding to those created by vibrating supports or -those created by the action of a pulsating force. The paper analyzes a case when the gaps (backlash) in the kinematic patra are not negligibly small but are of such a size that their effect on the behavior of the system cannot be ignored. In the presence of such gaps the problem of dynamic investi- gation becomes essentially nonlinear and the linear equations remain Card 1/2 valid only for separate intervals of the motion. A study of dynamic SOV/1 Z4-57-5-5228 Some Problems of the Dynamics of Mechanisms With Elastic Connections models proves to be the most expedient method of solving the problem. For a mechanism with a single gap the simplest general model is a system of two dif- ferent masses pressed together by springs of different degrees of stiffness clamped to a support. The author has found the conditions required for the follow- ing two different modes of operation: When the motion is accomplished without separations and when a separation between the masses does take place. The possi- bility of the existence of a stable periodic motion in the presence of separations is demonstrated. Tests conducted on a model in the form of two small cantilever beams of different stiffness placed on a vibrating table and loaded with different loads pressed together have confirmed -the theoretical formulas obtained.

Experiments are described whereby these calculations were tested. The mechanical a "as is shown in Fig,l. This consist* of a hollow cyllader (mass M) with closed ends. Thecylinder contains a ball (mass a) whose diameter is equal to the internal diameter of the hollow cylinder. The cylinder is attached to a spring (spring constant 1C.). Friction between the cylinder and the ball is negleoftd. The cylinder moves with one degree of freedom on a smooth horizontal table, the axis of the cylinder being also horizontal. Periodic motion of this system, which is characterised by successive collisions of the ball with the cut 1/7 left and right faces of the cylinder, are analysed subject to the condition that during a single period of M only two collisions between M and m take place. All friction On the theory of impact damping.

From these one must choose the solution corresponjing to the present problem. Thus, all solutions b giving C I, > 2 can be excluded. The period of the collisions should be Ir 21r To d < After the exclusion of the cases 2 the motion can be unambiguously determined only after an analysis of stability, The special case It a 1 is considered next and is illustrated in lig.3. The stability problem is considered f or p --~ oD and 04C R4C 1 where R is the coefficient of restitution. Arguments are put forward to su p rt the result that the vibrations corresponding to 1 T < 2 are stable.
