摘要:
针对动车组万向轴运用过程中出现的轴承润滑不良导致的动平衡超标及传动系统异常振动而影响行车安全的问题，研制了车载万向轴振动监控装置。通过在齿轮箱体和电机上安装振动传感器，以齿轮箱和电机测点的万向轴转频频段的振动信号为特征量，实时监测万向轴的健康状态；根据不同动平衡量级万向轴在不同转速下测点加速度响应的仿真分析、台架试验验证以及不同线路运行动车组万向轴现车振动数据统计分析，制定并优化车载报警阈值，并根据故障分级提供车载预警和报警信息。
Abstracts:
In order to solve the problems of excessive dynamic balance and abnormal vibration of transmission system caused by improper bearing lubrication affecting driving safety during the usage of EMU cardan shaft, on\|board cardan shaft vibration monitoring device is developed. By installing vibration sensors on the gearbox and motor, the vibration signals in the cardan shaft frequency section of the gearbox and motor measurement point are taken as the characteristic quantity to monitor the cardan shaft health status in real time. According to the simulation analysis of measurement point acceleration response of the cardan shaft on different dynamic balance magnitude at different rotational speeds, the test verification of the platform, and the statistical analysis of the present vehicle vibration data of the EMU cardan shaft running on different lines, the on\|board alarm threshold is established and optimized, while on\|board early warning and alarm information according to fault classification are provided.
