基于計算機仿真的汽車懸架性能參數設計：摘要 本文給出一種汽車面向行駛平順性分析的動力學仿真模型，應用仿真模型對某型號依維柯汽車進行了隨機不平路面輸入下的汽車懸架系統性能參數優化設計研究，得出了該車懸架系統性能參數優化結果。經該車優化后的道路試驗結果表明，優化后的汽車行駛平順性指標-車身振動加速度均方根值比優化前有較大改善，證明該優化方法對于懸架性能參數優化設計是可行的。

Abstract: A dynamical model of the suspension system for comfortable performance analysis is presented in this paper, the parameter optimization design of IVECO vehicle suspension on uneven random road is researched by means of the dynamical model, and the valuable optimization results are obtained. The road tests show that the comfortable properties parameter-R.M.S. of vehicle body vibrating acceleration of the IVECO vehicle with optimization suspension system is improved obviously, and the optimization method is feasible.
