摘要
分析基于空气弹簧的空气悬架系统,建立了车辆二自由度动力学模型,用Matlab计算出车身垂直振动加速度均方根值。构建了以加速度均方根值为目标函数的刚度阻尼匹配模型,对空气悬架的阻尼进行了优化匹配。仿真结果表明,车辆的行驶平顺性可明显改善。
A 2-DOF dynamical model of suspension system composed of air spring for vehicles was created.The RMS amplitude of vertical acceleration was figured out by Matalab and the optimization model was developed with arithmetic average of RMS amplitude of acceleration being as the aiming function.Then the stiffness and damping matching model based on an acceleration mean square value was constructed,and optimized matching for the air suspension damping was done.The simulation results indicated that the riding comfort of the vehicle has been improved evidently.
