摘要
将轨道高低不平顺视为平稳各态历经随机过程 [5 ] ,利用车辆 -轨道耦合动力有限元计算模型 ,对车辆 -轨道系统垂向随机振动做了计算 。
The track vertical profile irregularity is regarded as stationary ergodic Gaussian random processes.The vertical radom vibration of vehicle and track is computed on the basis of vehicle/track coupling dynamic FEM model.The analysis of system response is made in the time and frequency field.
