基于ADAMS/CAR二次开发模块车辆仿真系统平台,利用专家模块建立整车模型,模拟在某一车速、某型路面、某一前悬架刚度,进行整车在一定负载下的动力学仿真,在后处理模块中得出整车底盘质心三个轴向的加速度变化曲线,利用ADAMS后处理功能,通过快速FFT运算并结合相关客观评价算法,计算出三个方向的总加权加速度均方根值,以此为参量,评价整车行驶平顺性.这对轿车设计和相关参数的确定有重要的参考意义,为汽车平顺性等问题的研究提供参考.%Based on the reference index of the proprioceptive simulation performance motion platform provides, the typical movement charateristics of 3DOF and 6DOF platform are compared . It is shown that in satisfy conditions of the motion characteristics, the 3 - dof training - type simulator can substitute for 6 - dof simulator to provide real motion cues, thus reduce production and maintenance costs.
