Abstract

A general method to design ISD structure was introduced in this paper. Twenty-one kinds of new suspension structures feasible in engineering application were built by the method of putting energy storage elements, supporting elements and damper elements in different position. The general dynamic model of these structures was built then. The optimization of acceleration of sprung mass and dynamic tyre load was used to obtain the parameters of mechanical elements. By the comparison of the new and traditional suspension, twelve kinds of new structures were proved to be more excellent. The analysis of typical structures indicated that the method based on dynamic model and parameter optimization was general and universal to design ISD suspension structure.



Key words
