RAILWAY VEHICLE DYNAMICS--THE EMERGENCE OF A PRACTICAL THEORY

The purpose of this paper is to describe achievements made over the past 10 years by British railways in the field of railway vehicle dynamics. The authors feel that the significant change has been to bring the science of railway vehicle dynamics to the status of a practical engineering tool. The new theories permit the quantitative assessment of the behaviour of existing vehicles and the systematic exploration of possible new designs of advanced concept and performance. Section 2 of this report deals with interaction between wheel and rail, section 3 describes the equations of motion and subsequent sections cover in turn dynamic stability, motion in curves, and response to track irregularities and the mechanism of derailment. The nature of the engineering design problem is discussed wherein there are trade-offs between the principal performance indicators. Significant applications of this work to date are discussed.
