基于欧雷准则的某纯电动车悬架刚度优化匹配研究

在车型开发前期对悬架系统刚度、阻尼进行合理的优化匹配,不仅能缩短整车开发周期,同时还能提升整车性能,基于欧雷准则,以车辆二自由度模型为基础研究了前、后悬架刚度优化匹配的方法,并在某电动车动力学性能开发前期得以应用,通过实车试验与优化结果对比充分验证了该方法具有一定的工程应用价值,且能够大大缩短样车开发周期。

Study on Optimization and Matching of Suspension System Stiffness Based on Olley Criterion for Electric Vehicle

In the early stage of automobile development,the reasonable optimization of the suspension system stiffness and damping can not only shorten the development cycle of the whole vehicle,but also improve the performance.In this paper,the Olley criterion is theoretically analyzed,based on the two-degree-of-freedom model of vehicle,the method of optimum stiffness matching of front and rear suspensions has been studied,which has been applied in the early stage of the development of the dynamic performance of an electric vehicle,which fully verifies that the method has certain engineering application value and shortens the period of prototype adjustment and development.
