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

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.

Abstract :The cathodes of now-available pulse tubes become damaged when the pulses last
longer than 5,A6 see. 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.

recently simulated. particularly in connecton with visual observations. Among the
various approaches. the one due to Z. M. Braverman (Avtomatika I telemakhanika, 1962,

brief outline of this compsatness hypothesis, and on the basis of 24 Soviet and

ABSTRACT: The author gives a description of the working
organism of a program-controlled milling ma-
chine of the block type. 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

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. The
article will,be continued in Ur 3 of the 4our-
nalo There are 2 photos, and 4 sets of dia-
gram.

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.

ABSTRACTtYree and forced vibrations of an elastic systeal provided
with an impact damper, are considered. 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

equal to unity, It is assumed that as a result of an
initial excitation a periodic free motion of the above
type is taking place and its frequency in calculated.
