Abstract : 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 文摘: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，在时域和频域内对系统响应作了分析。
