ABSTRACT: The Gauss principle is utilised in cases when the
movement is studied of a mechanical system with finite
forces. For "impact forces" which act for a very short
time, the Gauss function Z and the respective
variational equation 6Z = 0 change. The author
attempts to derive the variational equation of the impact
theory by the direct methodwithout utilising the
Z function. An expression is given for the degree of
"forcing" Z' and it is stated that the equation 6Z' = 0
enables the determining of the speed occurring during the
impact, assuming the initial speeds and impulses as
constant. In this case the fundamental equation of the
shock theory can be written in the form expressed by
Eq.(1.1)9 p.106. By making various assumptions on the
physical properties of the colliding bodies it is possible
to derive from Eq.(1.1) all the known results of the shock
Card 1/3 theory. The possibility of using the same general approach

for solving a variety of differing problems facilitates
the solution of new problems which require a new
formulation. It is shown in this paper
what form the equation 6Z' 0 asSUMeB for deforming
bodies. The equation of the impact theory in generalised
coordinates q, q. can be read thus:
TO (k 19
qk
According to the Saint Venant theory an increase in
the modulus of elasticity E and a Aecrease in density
bring about unlimited rise in the stresses under
otherwise equal conditions whilst according to the new
theory the stresses rise at first to a certain maximum
and then decrease. Therefore, an equal permissible stress
for an equal shock load can be obtained in a plate with
low as well as with high values of VTM if a material
is chosen which has a higher modulus of elasticity and
a lower density. For inelastic bodies the assumed
hypotheses and method are applicable, i.e. it can be
assumed that for the first phase of the shock the

impulses and the components of the deformation speed
tensor is applicable and also all the conclusions derived
from the variational equation (1.1), p.106, for the case
of 6Z' - 0. Depending on the intensity of the internal
impulses, the first phase may end either with destruction
or with a change in the mechanical properties of the
colliding bodies or solely with a slight increase in the
temperature as a result of loss in the kinetic energy.
For the second phase the same equations are applicable
which describe the movement of the colliding bodies for
finite forces (the equations of the theory of plasticity,
of the elastic-viscous body etc.). If for the given
problem an accurate or an approximate solution of these
equations is found which contains arbitrary constants,
the latter can be determined from the condition of the
minimum of the "forcing" function.

TITLE: Gyroscopic Systemswith a Non-ideal Contact (Giroskopicheskiye

ABSTRACT: It can be stated generally that in the case of dry friction
the tangent Ps 1 being a component of a reaction Rs can
be expressed as:
I F f I N s
where N. - normal component of reaction, f - coefficient of
friction. Lagrange's equations can be employed for determi-n-
ing the reaction R. . The case can be shown of a system
where one of the elements remains in contact at the supporting
point P and N, F1, F" are the normal and the two tangent
components of the reaction R . The system has n degrees
of freedom and its position is determined by the coordinates
qn . When the velocity of the point P is v its components
v V~, V11 along the normal and the tangents of the reaction
Card 1/7 n, n

Gyroscopic Systemswith a Non-ideal Contact
can be found from Eq.(1.1) and the work of reaction 6A frDm
the expression (1.2). The equation of motion of the system
can be shown as Eq.(1.3). When the point P does not slide,
then V - 0 and the kinematic relations (1.4) are included
in Eq.(1.3). The Eqs.(13) and (14) will give the solution in
the ideal conditions, i.e. when the friction is not performirg
work. 1n the case of friction in boring and rolling, the c,52
ponents of the angle velocity w can be expressed as Eq.(1.5),
the forces of resistance by Eq.(1.6) (flI f 2 - coefficients of
friction of boring and rolling respect'-vely) and the work --s
Eq.(1.7). The last equation can be a,~Dlied in the equation af
motion (1-3) as it is shown in Eqs.(2.-:),(2.2) and (2.3). where
aik - function of coordinate q. . From this the following
is derived: 1) Reaction of an ideal contact depends only on
the instantaneous kinematic state of the system with the active
forces and it is not affected by the acceleration Ih , i.e.
reaction ca-n be defined at any insta-nt with no motion considered.

2) If the forces are those along coordinates, the reaction does
not change its value with change of sign of velocities.
3) In the case of cyclic coordinates and appropriate velocity
wk (large) being constant, then the terms containing small
velocities of the right hand side of Eq.(2.2) can be ignored.
Then the reaction of ideal contact can be compared with gyro-
scopic forces. 4) If there are small vibrations, then the
reaction will depend oaly on I tie coordinate qh provided the
active forces are the functiox.s of coordinates. All the above
is true when the oint P dofs not slide on the resist' 9
surfacel i.e. EqJ2.4) is satisfied Otherwise (Eq.(2.41n) not
sa4 sfied) the forces of fricii-on iF1 will be equal to
f1N and Eq.(3.1) takes plac( while Ej.(1.3) will take the
form of Eq (3.2), so that onl.,- Eq.(3.3 will remain of Eq.(1.4).
The Eqs.(3:2) and (3.3) suffi(iently describe the motion of
the system when the conditioni Eq.(3.1) are satisfied. Then:
(a) the normal of reaction N and forces of friction V and
F11 are not affected by acceleration, (b') if an additional
force Qh depends on the cooidinates, the normals of the
reaction INI change their value together with the change of
Card 3/7 sign of velocities, i.e. force of friction changes its value

Gyroscopic Systemswith a Non-Ideal Contact
and direction, (.V) when the coefficient of friction is small,
it is possible to predetermine the normals in order to add
them to Qh (Eqs.(4.1) and (4-5)). In this case, if the vel-
ocities q~ change their signs, the values of both the
reaction and the friction remain the same, (K) in the case of
both small vibrations and coefficients of friction, the nor-
mals remain constant or depend on the coordinates,
(d) if small vibrations are considered in relation to an es-
tablished motion, then the reaction can be expressed as a
linear function of velocity, (e) the sign of 6 - +-I in
Eq.(3.2) should be such that IN1>0 and N - elNl-. However,
the case may occur when this is not possible (Ref.1). Then
the inequality IN1>0 is upset 3.nd vn / 0 (Eq.1.1) and:

the two degrees of freedom and a vertical axis is considered

COVERAM The pamphlet pro-vides a basic introduction to computing machines, here
labeled as "electronic brains". A historic survey pxecedes the description of
the main types of mathematical machines. In this survey tbd author pays
tribute to Norbert Wiener. An explanation of principles underlying the theory
and practice of electronic computers follows. The author d1scusses t1w two main
groups of elect---onic computing machines, i.e., digital computers and analog
machines, and describes the arrangement and functioning of these machines, in-
cluding the arithmetical operations involved. The "SAPO" memory model machine,
the so-called "memory register", mentioned in the text is C,-ech. A diagram is
given. Other examples quoted are nr)n-Czech. The similarity between the brain

ABSTFACT: The selective assembly of diesel engine fuel pump plungers
and cylinders is at present carried out by finding a plunger
which enters the cylinder to about 1/3 of its length followed
by lapping, which is completed when the plunger enters freely
for the vUle of its length. The judgment is subjective. The
assembly is then inspected to verify its free movement after
washing the component in petrol and diesel fuel. The final
inspection test consists of measuring the leakage rate of a
fine oil under a given piston load. Observations at the
Noginsk plant of fuel supply equipment (Nogiaskij Zavod Topliv-
moy Apparatury) and at the Kh%kkov Tractor-PlIent (Kharkovskiy-'.
Traktorniy Zavod) KhTZ have revealed the main difficulties of
inspection. The precise measurement by a pneumatic comparator
is recommended to reduce materially the labour caa-mming sele-
ction during 4ssembly and the work involved in lapping.

TITLE: Use of Epoxy Resins for Assembling Machine Pa ts
PERIODICAL: Plasticheskiye massy, 1960, No. 8, pp. 34-39
TEXT: At the laboratory of the Kafedra "Tekhnologiya mashinostroyeniya"
MVTU im. Baumana (Chair of Mechanioal Engineering, Moscow Higher Technical
School imeni Bauman), the usability of epoxy resins for connecting
machine parts was investigated. Dowel joints (Figs. 1 and 4) were sub-
jected to tensile and torsional tests, and tube connections (Figs. 2, 3,
5) were subjVcted to tensile and density tests. The loadiqg methods are
outlined in Fig. 6. As G�-2 (BF-2) and 64 -4 (BF-4) &Lues-7did not give
satisfactory results, the first of the epoxy resins 3A-5 (ED-5) and,3A-6
(ED-6) was used. Malsic anhydride, polyethylene polyamide,and hexamethyl-
ene diamine were used as hardeners. 150 - 1600C was found to be the op-
timum temperature for hardening. From Fig. 8, the following values of the
breaking load at this temperature were found: with 20% hexamethylene
diamine, about 2800 kg; with 30% maleic anhydride, about 3000 kg; and

with 8% polyethylene polyamide, about 2600 kg. At a lower content of
polyethylene polyamide, values up to 3200 kg could be obtained (Fig. 7).
but in this case the resin becomes so thick that pouring into narrow
clearances is made difficult. Fig. 9 shows that the optimum duration of
heating for maleic anhydride is 30 min, and for the two other hardeners
it is 60 min. Without heat treatment (in construction work or in the case
of very large machine parts), hexamethylene diamine or polyethylene poly-
amide may be used. It follows from Fig. 10 that the greatest breaking
load was obtained at 0.2 - 0.3 mm clearance. The dowel joints withstood
the torsional moment (up to 700 - 1300 kg-cm) during the tightening of
screws. Fig. 11 shows the dependence of the breaking load on the clearance
in the case of thin-walled tubes: Optimum at 0.05 - 0.1 mm. In the case
of gas- and water-pipes, 1 to 2 mm clearance gave sufficient strength.
In this case, Viniplast powder, foundry dust, quartz sand, cement, metal
shavings, and metal powder were used as fillers. The latter gave the best
results; but also with 50fa quartz sand, the breaking load was not below
1500 kg. 3/4 and 1 3/4 inch tubes gave a breaking load of 2600 to 5000 kg
with ED-5 and hexamethylene diamine. The tubes remained tight at 12 atm.
Repeated heating of hot-hardened tube connections (Fig. 12) at 100 C
caused the breaking load to decrease, but this remained within the

permissible limits. Cold-hardened tube connections did not withstand
this test. Cooling down to -70 0C was without influence upon strength.
The author discusses the reduction of expensesby using resin to be ex-
pected as a result of the elimination of surface treatment and thread-
cutting. The material costs for resin are-3 kopecks per dowel joint, and
for a connection of thin-walled tubes 12 kopecks. Mention is made of the
luting of bicycle frames at the 'Wifall works in Eastern Germany. There
are 12 figures and 1 Soviet reference.

SOURCE: IVUZ. Mashinostroyeniye, no. 2, 1966, 38-42 Id
TOPIC TAGS: stress analysis, pipeline, hydraulic equipment, turbojet engine, metal
joining, stress concentration, fatigue strength
ABSTRA# : The authors study methods for raising the safety factor of pipelines with
A"hipples in turbojet engine bydraulic systems underk variable stresses. The
-hram
pipelines and nipples in this study were made of M18Ngrl4teel and brazed by high
frequency current and oxyacetylene torches using PZh~5_-8 'high-temperature solder.0
Such joints can withstand pressures of more than 500 kg/cm2 and uniform heii~i UP to
7000C. It should be added that this type of union can function under extreme vibra-
tion. Turbojet engine pipelines are most susceptible to vibration &rising from rotor
imbalance and gas stream pulsations. Strain tests of 60 pipelines show that the
overall maximum level of vibration stresses is 5-6 kg/=2. An expression is given
L 05696-67
ACC Mitt AP6022863 .121
for calculating the safety factor of pipelines used under variable load conditions.
This is based on the fact that variable loads change according to an asymptotic law.
In finishing pipeline systems, a safety factor of at least 1.3-1.4 is desirable.
This can be achieved by decreasing variable stresses and lowering the static compon-
ent of normal stresses thus raising the fatigue limit. Tests show that the fatigue
limits are approximately the same in pipeline bending for tub* with internal fluid
pressure of 100 kg/cm2 and atmospheric pressure. The fatiguellimit of pipelines is
a function of the absolute dimensions of pipe cross sq;c-tion and local stress concen-
trators. It is shown that the experimental method is most accurate in determining
the fatigue limit of pipelines. Data are given for fatigue limits of_yVious dia-
meter pipelines and experimental coefficients of stress concentratiodjfor nipples.
The minimum safety factor used for existing turbine engine pipelines is 1.75-2.5.
The main problem to be solved is that higher safety factor values should not be ac-
companied by increased weight and reduced efficiency of the system. Orig. art. has
4 figures, 2 formulas.
