基于同一转向架历史对比与同一列车横向对比的转向架状态监测

转向架状态监测一直是客车行车安全监测系统中的重点监测对象,对保障旅客列车行车安全具有重要意义。同时转向架状态也是监测工作中的难点,转向架的内部结构与列车运行环境的多样性造成了其动力学性能特征复杂,难以用同一标准的参数限定值来判断其性能优差。利用绝对评判与相对评判方法结合,对转向架性能采用整列车横向对比和单车历史对比的方式,直观有效的分析了转向架运行的振动情况和性能的变化趋势。

Bogie Condition Monitoring Based on Comparing Historical Date of One Bogie and Date of All Bogies in One Train

Bogie condition monitoring is the main object of passenger car running safety monitoring system,and it also is the difficulty of monitoring job.Because of bogie structure and diversity of vehicle running environment,bogie's dynamic characteristics are complicated.And it's not accurate to use the same standard parameter to judge a bogie's performance.Taking Absolute and Relative method,comparing historical date of one bogie and date of all bogies in one train,we can diagnose bogie's running state and its tre...
