Abstract

Inerter-spring-damper suspension has the charateristics of stiffness,damping and inertance. Match between the ISD suspension and vehicle is a new problem of vehicle system dynamics. The mechanical network model of suspension system was bulit according to the electrical and mechanical analogy and the general rule of match between the ISD suspension and vehicle was obtained based on maximum power transmisson theory. The rule was demonstrated by using traditional modeling approach. On this foundation, the parameter matching method of ISD suspension was put forward. The results show the proposed method can make the suspension absorb vibration energy from the road excitation with maximum power at the offset frequency of vehicle body. Therefore,the energy absorbed by vehicle body is minimum，the vibration at the offset frequency of vehicle body is suppressed effectively and the vehicle ride comfort is improved.

Key words
