摘要：

In order to improve the ride comfort of vehicles, an inerter was applied to a vehicle suspension system to build “inerter-spring-damper” (ISD) suspension. The structure of the ISD suspension was determined by using a network synthesis method. The impedance transfer function of the ISD suspension was obtained with the root-mean-square (RMS) of the vehicle body acceleration as the ride comfort index. It could be physically realized by using passive elements such as inerter, spring and damper. A quarter car vehicle model was built. By using the multi-objective optimization method, structural parameters of the ISD suspension were optimized. On this basis, the performance of the suspension system was verified under random and pulse input. The results show that in contrast to conventional suspension, the proposed suspension has a better dynamic performance. The RMS of body vertical acceleration is reduced about 26.83%. The ISD suspension can suppress vertical vibration of vehicle body within the frequency of 1-3 Hz and improve the ride comfort of vehicles. © 2016, Editorial Office of Journal of Vibration and Shock.
