车辆——轨道耦合系统随机振动分析

摘要

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.%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。
