General Introduction to a Programme of Dynamic Research

This paper is a general introduction to a series of progress reports on an experimental and analytical investigation of the fixed-control directional characteristics of automobiles, and those mechanical properties of tyres used in the analysis of car stability and control. The programme under consideration utilizes aeronautical and control-theory techniques in deriving and substantiating equations of motion for the automobile. In addition, a six-component tyre-testing machine for static and dynamic tests on flat-road surfaces is described, and tyre data for a wide range of slip and camber angles are presented.In this initial paper an historical background of technological progress in automobile handling is given in a framework of vehicle handling in general, with particular reference to the science of aeroplane stability and control. This presentation enables a relative evaluation of automotive progress. The specific research objectives of the programme are then examined. A summary of dynamic concepts and...
