TITLEs Technological process of casting crankshafts for the AB-30 (DV-30) engine at the Vladimorovskiy traktarAyy zavod (.Vladi- mirov Tractor Plant)! PERIODICALt Liteynoye prdzvodstvo, no.,.10,-196o, 16,','-' 17 f TEXTs Based on the experience of the Khar I kov' S orp,i molot"jiPlant, the Vladimirov Tractor Plant started the casting of'orajakshafts for the DV-30 engine. The authors enumerate the defioienoies oactirring during the casting of the crankshaft for the 6MA-7 (SMD-,7) engine at;' the. "Serp i molottl Plant and point out that the elimination of black spots by Increasing the machining tolerances is not expedient; therefore, it is n:ecessary to pre- vent the origination of black spots which can be attained by the desulfuri- zation of the cast iron, bringing the $-content down to 0.008 - 0.005%. This is possible if the cast iron is smelted in a bdaio electric furnace. AttemptB were made to eliminate the technical difficulties connected with the Card 113 S/128/60/000/010/008/616/zx Technological process of casting crankshafts... A033A133 production of magnesium-modified cast iron by using other modifiers,1ikez' cerium, tellurium, oalcium, strontium, lithium, etc. Tests proved oel~ium' and foundry alloys on the base of cerium to be the most suitable modifiers, In comparison with magnesium, cerium offers the following advantagess~no metal ejection during modification; the assimilability of cerium amounts:to not less than 30%; lower sensitivity of the cast iron to demodifiers; in- significant cast iron temperature drop during the modification process (be- tween 20 and 4000; uniform distribution of sulfur over the casting and tLb- sence of black spots on its surface. In order to maintain-a constant;ohem- ical cast iron composition during the investigations basic cast iron of the following chemical composition (in %) wag smelted in a 3-tdn acid electric furnaoet 3.5 - 3-6 C; 2.0 - 2.2 Si; 0.8 - 1.0 Mn; knot more than M4 S. Then this cast iron was remelted in a 50-kg capacity Iacid induction furnace. The metal was heated to 1,480 - 1,4500C, the modifiers (compositiont 5 - 7% Mg, lWo Fe, 40 - 50~6 Ce, the rest rare earths) amounting to 0.4 - 0-35~0 of the liquid metal weight was put on the ladle bottom.. To remove cementite' formations and increase the mechanical properties, the cast iron Was subje.0i. ed to additional modification by 0-3 - 0-40/6 CH (Si) 75 fer�ouilicium.. After two minutes holding in the ladle the metal was poured into the crankshaft Gard 2/3 Sll28V6,010001010100810161Xx Technological process of casting crankshafts... A033/433 shell molds.

Grigoryan's article "Stating of,dynamic problems for ideal plastic media" Periodical Prikl. mat. i mekh., 19) Nov-Dec 1955, 733 Abstract The present authors remark that S. S. Grigoryan carried out'interesting investigations of the equation of state of.plastic medium, wh~ich~ equation was proposed by them ("Dynamics of~grounii masses," DAN,SSSR, 95, No 4, 1954), and his results deserve atiention. Grigorya.h pointed out that the energy condition on the surface of strong discontinuity is fulfil-led during the entire time of the process only if in'the. external region the pressure equals the critical pressure, as~was assumed in the authors' work, and he also made a conclusion cbncer'ning the impossibility ofthe existence of a certain zone III etc., As;,a result Grigoryan concludes categorically that the:stated problem can- not be solved by.means of the authors' equation of state. The present authors cannot agree with the categorical character of this conclusion. The authors consider their scheme as a limiting scheme and not as'com- pletely solving the problem of deformation of densification of grounds. The entire problem consists in whether their description gives the main outlines of the phenomenon of dynamic densification of grounds'. The problem remains open. Submitted .:ZVOLINSKIT.

For the purposes of their examina- tion of these problems the medium is considered to be ideally' horno- geneous. They examine two types of driving forces: 1) Forces actin g from within the elastic medium [ three -dime ns ion:al (spherical; Transl. Ed. Note)] waves and Z) forces acting on them free boundary of a semi- infinite medium (surface waves).

Also, the authors elucidate the law whereby the intensity,;of the' emissive powe:r must increase with the observer' s distance from the emitter. An account is given of ob- servation methods used ,and the results obtained thereby!, in coal mines of the Don- bass. While, in general, the author's experimental findings do support their theo- retical conclusions, the wave - ~ttenuatlon picture as traced by1hem is rendered more complicated in some respects by the operation of interference and resonance factors. Included are experimental data on the propagation distance of elastic waves (in the 300-1, 000 cps frequency range) in Donbass coal seams and inthe rock enclosi Ing them.

In earlier work, them author of this paper and Zaytsev, L.P. (Refs.2 and 3) found that this method is very suitable for studying the near front zone of the wave and1eads to physically clear results but they studied only~very simple problems. G. S. Markhasev, G.S. (Ref.4) also.6onsidered them ~ reflection and refraction of spherical waves on a plane boundary of two elastic media; he developed a method of separating the asymptotic part of theiwave field. However, he did not consider important features of the wave field and his final results arein a too general.

In this paper the author shows that tile method of, functionally invariant solutions can be 'applied f or the ne&r front zone of the waves enterinp; on the backgrouind of the preceding wave field in addition to the firsts entries of the reflected waves and primary waves. Using the method of functionally invariant solutions, the : author studies the reflected and the main.waves forming at a plane boundary of division of two elastic media., The author also describes a method of separating the: asymptotic part of the field in a different formulation which &Lves clearer results and the finalform of which is convenient for practical application. ' The problem of reflection and refraction of elastic waves on a plane. boundary has also,been studied by other authors (Refs'.5-8) who used different variants of the~method of sub-division of the variables. However, for the given problem, the method of functionally invariant solutiohs leads to the same final formulae as the sub-divislon of the variables and, therefore, the formulae arrived at in this paper T are not new; they approach closely those.published by, Card 2/3 Ogurtsov, K.

ABSTRACT: The problem was investigated in Ref A)of the reflection and the refraction of sphbrical waves at~a plane boundary between two elastic half-spaces. The solution of this pro- blem was derived by the method of functionally~ invariant ~ solutionsp and the possibility of approximately describing ~he reflected wave PP in the region of incidence was indicated. In the present paper the author considers the approximate description of the reflected wave, PS and the direct waves in the region of incidence. . The statement of the problemg the choice of a frame of reference and them choice of symbols are as in Ref.(J). It'is assumed that at a distance, z0 from the plane boundary division there consists a point source of disturbance emitting a sphericalf longitudinal wave. The source strength is Card /,,given by: Reflected and Direct Waves Occurring at the Plane Boundary of Division Between Two Elastic Media.

This is possible if the cast iron is smelted in a bdaio electric furnace.

Grigoryan's article "Stating of,dynamic problems for ideal plastic media" Periodical Prikl. mat. i mekh., 19) Nov-Dec 1955, 733 Abstract The present authors remark that S. S. Grigoryan carried out'interesting investigations of the equation of state of.plastic medium, wh~ich~ equation was proposed by them ("Dynamics of~grounii masses," DAN,SSSR, 95, No 4, 1954), and his results deserve atiention. Grigorya.h pointed out that the energy condition on the surface of strong discontinuity is fulfil-led during the entire time of the process only if in'the. external region the pressure equals the critical pressure, as~was assumed in the authors' work, and he also made a conclusion cbncer'ning the impossibility ofthe existence of a certain zone III etc., As;,a result Grigoryan concludes categorically that the:stated problem can- not be solved by.means of the authors' equation of state. The present authors cannot agree with the categorical character of this conclusion. The authors consider their scheme as a limiting scheme and not as'com- pletely solving the problem of deformation of densification of grounds. The entire problem consists in whether their description gives the main outlines of the phenomenon of dynamic densification of grounds'. The problem remains open. Submitted .:ZVOLINSKIT.

For the purposes of their examina- tion of these problems the medium is considered to be ideally' horno- geneous. They examine two types of driving forces: 1) Forces actin g from within the elastic medium [ three -dime ns ion:al (spherical; Transl. Ed.

While, in general, the author's experimental findings do support their theo- retical conclusions, the wave - ~ttenuatlon picture as traced by1hem is rendered more complicated in some respects by the operation of interference and resonance factors. Included are experimental data on the propagation distance of elastic waves (in the 300-1, 000 cps frequency range) in Donbass coal seams and inthe rock enclosi Ing them.

In the present paper the author considers the approximate description of the reflected wave, PS and the direct waves in the region of incidence. . The statement of the problemg the choice of a frame of reference and them choice of symbols are as in Ref.(J). It'is assumed that at a distance, z0 from the plane boundary division there consists a point source of disturbance emitting a sphericalf longitudinal wave. The source strength is Card /,,given by: Reflected and Direct Waves Occurring at the Plane Boundary of Division Between Two Elastic Media.
