摘　　要：为提高履带车辆的平顺性,对车辆悬挂系统参数的优化方法进行了研究。首先建立以驾驶椅位置联合加权加速度有效值为评价指标的履带车辆平顺性评价模型,并进行了实验验证。在此基础上,运用径向基函数法构建了悬挂系统主要参数与平顺性评价指标之间的响应面模型。利用响应面模型,选择自适应模拟退火优化算法对悬挂系统参数进行优化设计。优化后车辆的平顺性有所提高,证明了论文提出优化方法的可行性。与直接优化法相比,响应面法具有适应性强、效率高的优点。To improve tracked vehicles＇ ride comfort,an optimization method for suspension system parameters is studied.First a ride comfort evaluation model of tracked vehicle is built,in which the effective value of acceleration at the driver seat is selected as the comfort evaluation index.Then,a response surface model between suspension system parameter and comfort evaluation index is built by using radial basis function method.According to the analysis results,optimization design is carried out for suspension system parameters by using adaptive simulated annealing optimization algorithm.The optimization results show that the ride comfort of tracked vehicle is improved obviously,and the optimization method proposed in this article is feasible.Compared with direct optimization method,this method has more compliant and high computational efficiency.
