摘要
在八自由度整车振动模型的基础上提出了汽车舒适性的一种统计算法 .该算法在频域上利用 AR模型离散生成随机路面输入 ,通过数值求解动力学方程并运用统计方法来确定有关指标 .算法考虑了悬架阻尼的变化情况 ,更为符合实际工况 .
Based on the eight DOFs vehicle vibration model,a statistical algorithm for vehicle comfort is presented.With the algorithm the discreting road excitations are generated by means of applying AR model in frequency domain,and related parameters are given by solving the dynamic equations with digital method and statistics method.Different cases of suspension damp can be considered to accord with practical working conditions by this approach.The calculation examples verify the effectiveness of the algorithm.
