摘要
介绍了轨道交通列车车轮踏面清扫器的结构与功能。参照IEC 61373:2010的要求,对实车采集的振动载荷进行了等效计算。设计了试验方案,对踏面清扫器进行了横向、纵向和垂向等3个方向的模拟长寿命振动试验、冲击试验和功能性随机振动试验。结果表明,在目前的试验条件下,踏面清扫器各零部件未出现明显裂痕,性能未受到影响。
The structure and functions of rail transit train tread cleaner are introduced.According to the requirements of IEC 61373:2010 standard,an equivalent calculation of vibration load collected from real vehicle is carried out.Then,a test scheme is designed,in which simulation long-life vibration test,impact test and functional random vibration test of the tread cleaner in transverse,longitudinal and vertical directions are implemented.The test results show that under present test conditions,no obvious cracks in each part of tread cleaner are detected,and the performance of tread cleaner is not affected.
