| 摘 要： | 为评价某观光车的平顺性,利用MATLAB的遗传算法优化工具箱,对后悬架的某两片式等截面钢板弹簧进行优化设计.以多体动力学理论作为基础,应用ADAMS/Car建立包括前悬架系统、后悬架系统、转向系统、轮胎系统和车身系统的整车动力学模型.对观光车整车模型进行脉冲路面的平顺性仿真,得到质心位置的垂直方向上的最大加速度曲线对比.通过分析仿真结果,装用优化后的变截面钢板弹簧的整车平顺性有较大提高.

| Abstract: | In order to evaluate the ride comfort performance of one sightseeing vehicle, the leaf spring was optimized by genetic algorithm with the MATLAB software. The whole vehicle dynamics model is established in ADAMS/CAR, including the front suspension system,rear suspension systems, steering systems,tires system and body, based on multi-body dynamics theory. The model is used to do the simulation under pulse inputs, to get the acceleration curves of vertical direction. After analysis of simulation result, the optimized taper spring can improve ride comfort of this vehicle. |
