轨道车辆运行过程中人体振动仿真研究

在人体振动模型研究基础上,建立了人体轨道车辆运动方程。利用来自二系悬挂的冲击输入以及来自轨道的随机干扰输入,研究在车体上以及人体头部和内脏引起的响应。结果表明:人体的振动与车体的振动有较大的差异,横向人体振动较大,垂向人体振动较小;人体头部的横向振动较内脏的振动大,垂向头部振动较内脏的振动小。

VIBRATION SIMULATION OF HUMAN BODY ON RUNNING RAILWAY VEHICLE

The dynamic equations of a human body and a railway vehicle are setup based on study on human body vibration model. The responses of the human body and the vehicle body are investigated and analysed with disturbance inputs: the impulse from one of the second suspensions between the vehicle body and the bogie frame, the random disturbance from all wheels. The result shows that the railway vehicle body vibration is quite different from the human body vibration, the lateral vibration of the human body is stronger than that of the vehicle body while the vertical vibration of the human body is weaker than that of the vehicle body, the lateral vibration of the human head is larger than that of the buman viscera but the vertical vibration of the human head is weaker than that of the human viscera.
