Ed.t M.I. Oranskiyj Tech. Ed.: A.A. Zabrodina. PURPOSE: This book is intended for engineers designing and using voltage regulators and also for scientific workers and students of electrical-engineering vuzes and departments. COVERAGE: The author explains the theory of ferroresonant voltage regulators. He describes methods of designing the basic circuits of ferroresonant voltage regulators and points out some of their applications. In the foreword the apthor states that he followed the terminology recommendations of the Rublication,"Terminology of the Theoretical Electrical Engineering. Farroresonant phenomena have been investigated and described by P.L. Kalantarov. Applica- Card 1/6 Theory of Ferroresonant Voltage Regulators sov/1676 tion of ferroresonance to voltage regulation has been described in papers by S.P. Pivovarov, V.V. Kovalevskaya, M.G. Lozinskiy, Ye.V. Sazanov, A.G. Lurlye, G.K. Yevdokimov, and others. According to the author, however, there is still no unified, genera4 and systematic theory of ferroreBonant regulators. The author attempts to elaborate such a theory. The author thanks Professor N.N. Shumilovskiy, Doctor of Technical Sciences, and Engineer I.G. Golldreyer for their comments. There are 73 references, 47 of which are Soviet, 14 German, 10 English and 2 French. TABLE-OF CONTENTS: Foreword Introduction Symbols. Ch. 1. Ferroresonant 1. Description of 2.

The condenser machines can be linked together and therefore made more powerful and suitable for use with a complex network, as well as with sepa- rate nets. The limits of resistance to detonation depend upon the capacity of the condensators and the voltage with which the are charged, also upon the type of electrode tonNors and upon the layout of the net. KPM-1 has a limit of resistance equal to 350 ohm Card 1/2 SOV/176-58-7-12/17 Estimates of Electric Wiring Used in 71orking Condenser Exploders I and with parallel connections of 5 electrodetonators to 14 ohm. In the KPM-2 unit, the corresponding fi- gures are 900 om and 50 om. The author givEs examples' of the limits of resistance in the individual settings. There are 5 diagrams and 1 Soviet reference.

Moscow-Lenin- grad, Mashgiz, 1953, pp 1-5 ABSTRACT: A short exposition of the development results of calculation methods for the creeping of non-uniformly heated turbine disks of an arbitrary profile and turbine diaphragms is given. The calculation of the unsteady creeping of a turbine disk is based on the variation method proposed by L.M. Kacha- nov. The distribution of stresses in the state of stationary creeping, Recessary for this method, is determined by means of the numerical integra- tion of the system of two equations with respect to two functions, through which the stresses and the deformations in the disk are expressed. To satis- fy the boundary conditions It is necessary to integrate the system 2 - 3 times. The calculation is based on the equations of the fluid dynamics. The steady creeping of a turbine diaphragm is schematically considered as Card'1/2 a semi-ring of constant thickness, at an arbitrary relation between the SOV/125-59-1-830 The Development 14ethods for Calculating Turbine Parts Under the Conditions of Creeping creeping rate and the stress. For the determination of the maximum deflection of the dia- phragm. a very simple method by means of two given graphics is proposed. The effect of the vaneAeformation can be taken into account, but the calculation appears very difficult. A.G. Kostyuk Card 2./2 LURIYE, A.I.

At first he gives a representation of the dissipation function which is valid also for different forms of the friction lawn A second short remark concerns the analytic representation of the kinetic energy of acceleration of a body rotating around an axis. In a third remark the author gives investigations f~r the determination of generalized forces of revolution. By a suitable kind of representation it is possible to determine separately each of the generalized forces of reaction from one equation. The most detailed remark refers to the equation gi- ven by Darboux [Ref 37 . With the aid of the complex parame- ters introduced by Klein and Cailey [Ref 4] it is possible Card 1/2 Remarks'on Analytical Mechanics 40-21-6-4/18 to bring the Darboux equation intb a particalarly simple form. Its solution can be reduced in special cases to the solution of a Riccati differential equation. In special cases even an integration by simple quadratures can be obtained. The auth*r calculates more detailed such a special case which refers to the motion of a quick, symmetric gyroscope around the axis of symmetry.

In this, the authors apply the properties of neighborin curves, focusing at points along the direct curve the,solution of the Hamilton equations). It Is shown that a modifi- cation of the Hamilton principle leads to a study of the extrema of a certain functional without giving the character of the extremum. This, the authors note, has to be done on the basis of an independent in- Card 1/5 vestigation. They first show that the Hamilton action: Application of.,Integral and Variational 77983 Principles of Mqchanics to Vibration SOV/410-24-1-11/28 Problems S~ L(h Card 2/5 assumes a minimum wher, vj,ken along a path which is a solution of' the Hamilton equations: 3 H air jp. 9 ps Here L is the Lagrangian,and p S andqs are the generalized momenta and coordinates of the system which is assumed to be conservative with holonomic constraints independent of time. It is assumed that a first time t 1 exists after t 0 for which a certain determinant A (t) vanishes. This implies the existence of a solution of' the system of equations for the unknown coefficient8 which arise In -repr-e- senting a solution of the variational Hamilton Application Of' DILCL~t,al Z-11-ILI Vacl.A1011,11 PL'1(JCIj)l0o of' Mechanlc.,, to Vibc,--ilJon 1130V/110-211-1-11/28 equations in terms of' a pat-ticular solution. of the variational equations. This in turn implies the exist- ence of a family of isochronous curves which emanate from the initial position qS (t0) on the direct curve and Intersect the direct curve at q (t*). On all s 1 of theoe curves, the action up to terras of second order, inclusively, is the same. However, the non- vanishing of 6(t) for t < t < t* and the positive- 0 definiteness of the quadratic form: I YJ-021f 11114k (1.3) ti k=i j1_1.Y1_11 Is then shown to guarantee that the second variation 8 2S for, any neighboring path starting from the initial position qS (t0) is positive and, hence, that the . action is a minimum on the direct path. Here p + u Car-d 3/5 3 s Application of Integral and Variational 77983 Principles of Mechanics to Vibration sov/4o-24-1-11/28 Problems are the momenta for infinitely close motions. When the position qs(tl) is attained after passing through qs(t*1), the action will no longer be a minimum. This is applied to the small vibrations about equilibrium of' a conserva-3ystem. A formula for the focusing post- tion q (t*) is obtained using an explicit solution s 1 qs(t), ps (t), and corresponding The closest t turns out to be the semiperiod of the principle vibration of LrreateBt frequency; the Hamilton principle holds only in the sense of stationary value.

The motion of a "supporting" body in an inertial axes system is given in terms of vectors o-f linear initial velocity, associated axes and angular velocity. The motion of each "supported" body is expressed with reference to axes fixed in the "supporting" body in terms of vectors of respective linear velocity of the origin of the axes of the "supported" body and its angular velocityo Examples are given illustrating the applicat-ion of the derived equations.

Ed.: D.R. Merkin; Tech. Ed.: K.F. Brudno. PURPOSE: This book is intended for students at technical universities, physicists, and engineers concerned with problems in ahalytical mechanics. COVERAGE: The book covers much of the material traditionally taught in courses on analytical mechanics (general equations of motion of holonomic and nonholonomic systems, variational principles, the theory of canonical transformations, canoni- cal equations with the theory of their integration (theorem of Hamilton- Jacobi3, integral invariants, the theory of the last factor'Ietc.). Particular attention is given to topics having closq connection with engineering problems. The reader is assumed to be familiar with the basic laws of mechanics. The book stresses the application of analytical mechanics to real problems; to this Card 1/301 Analytical Mechanics SOV/,,5768 end considerable attention is given to methods of introducing generalized coordi- nates, the theory of finite rotations, methods of calculating kinetic energy and energy of accelerations, the potential energy of forces of various charactery and the consideration of drag forces. Following the introductory chapters, t~l-.e book considers methods for setting up differential equations of motion of holo- nomic and nonholonomic systems in various forms, wherein questions of their in- terrelationship are discussed. Detailed consideration is given to problems of determining the reactions of constraints and to some problems of analytical statics. The book also considerst geometrically the motions of a material system as the motion of a characteristic point in a Riemann space. This material is used subsequently in problems of perturbation theory. A Spe-,ial chapter is devoted to the dvnamics of relative motion to which belong many applied problems. In addi- tion, the book considers canonical equations, canonical transformations2 and problems of integration. Considerable space is given to the perturbation theory and its various applications. The last chapter is devoted to the principle of Hamilton-Ost,rogradskiy, the priniiple of least work of Lagrange, and the theory of perturbation of trajectories. General methods are explained by examples. These include the problem of motion of a solid body on a moving base, the moti, of a solid bocty with a cavity filled by a fluid., the problem of motion of a roe Card 2A7 Analytical Mechanics SOV/5768 the application of the Hamilton-Ostrogradskiy principle to systems with distri- buted massesp ate. Specifically considered are problems connected with the par- turbed motion of an artificial earth satellite. To assist the reader, the book s.ummarizes the most important aspects of the theory of matrices and tensor calcu- lation. Part of the book is based on lectures on analytical mechanics and the theory of vibrations given by the author for more than 20 years to mechanical specialists of the Physics and Mechanics Department of the Leningrad Polytechnic Institute imeni M.I. Kalinin. Although the book is not coordinated with The official program requirements and is not intended as a textbook for schools of higher learning, the author feels that it will be of use to students and to scientific workers in many fields of engineering.
