摘　　要：基于Adams和Matlab应用改进响应面法对悬架结构参数进行了优化。在Adams/Insight软件中进行了设计参数的灵敏度分析。针对灵敏度较大的设计参数,建立了车轮定位参数在车轮跳动过程中最大变化量的二阶响应面近似数学模型,并对该模型进行了可靠性分析。应用编程实现对响应面数学模型的优化求解,对优化前后的仿真结果进行了对比。对比结果显示了该方法具有较好的准确性和有效性。The suspension structural parameters were optimized based on the improved response surface method and Adams and Matlab. The design parameters＇ sensitivity was analyzed by Adams/ Insight. For the design parameters with greater sensitivity, a second-order response surface approximate model of the wheel alignment parameters maximum variation in the wheel hop was established and analyzed. The optimization problem was solved by programming. Comparing the simulation results with the one before optimization, the results show that the method has good accuracy and effectiveness.
