Ball bearing lubrication

Ball Bearing Lubrication, by Bernard J. H a m r o c k and Duncan Dowson, Wiley-Interscience, New York, 1981. ISBN 0-471-03553-X, xxv + 386 pages, illustrated, hard cover $36.95. This b o o k is the latest authoritative word on the application -- mainly to ball bearings -- of elastohydrodynamics, that area of tribology which, though recognised for some thirty years, was formulated into a useful working theory only a b o u t t w e n t y years ago by one of the authors, Professor Dowson, in collaboration with Professor G.R. Higginson. The technical content of the b o o k is therefore largely original and of unquestionable excellence and it provides essential reading for bearing designers, users and in fact anyone concerned with high-pressure rolling contact. Add to this the extensive list of references included along with a digest of relevant experimental and field work and y o u have just a b o u t the ultimate source b o o k on this interesting subject, which sets o u t to explain why intensely loaded rolling/sliding contacts (in particular of elliptical shape) can function long after they would normally be expected to fail. The b o o k is very well designed, with abundant diagrams which are informative and of good size. There are many useful computational data with experimental support and performance prediction. Metallurgical and Production aspects are treated and students of industrial history will find the first thirty-four pages (chapter one) of special interest. The final chapter throws light on particular associated problems of elastohydrodynamic lubrication, for example gearing, infinitely-variable-speed ("friction") drives and, even, human skeletal articulation. One particularly helpful feature of the treatment is the expediency of providing a closing section to each chapter which sums up admirably the content therein. In short, this is a thoroughly sound b o o k which will find favour with researchers, teachers and field engineers alike. N. MAW
Vibration Analysis and Control System Dynamics, by C.F. Beard, Ellis H o r w o o d , Chichester, 1981. ISBN 0 - 8 5 3 1 2 - 2 4 2 - 3 , 1 6 9 pages, illustrated, hard cover £16.50: paper edition £5.90/$12.95. This b o o k follows the general pattern favoured by teachers of dynamics, in that it treats vibration and control together. There is much sense in this, because the t w o -- apparently unrelated -- topics are governed by similar equations of motion. This is obvious to an experienced dynamicist b u t a student, meeting the c o n c e p t for the first time, needs to be convinced that there is more to it than mere educational expediency in these days of full syllabi. The author has appreciated this and he supplies an introductory section on mathematical modelling which is the unifying theme. It is a pity, though, that the introduction is so short, because mathematical modelling in engineering is what distinguishes the art from the science and there is al-
