Influences and Evaluation Method of On-board Equipment on Metro Car Floor Vibrations

Abstract

Abstract: Through the workshop and loading vibration tests and analyses of a metro vehicle auxiliary converter, the floor vibration causes of metro car were determined, and the irrationality of on-board equipment vibration evaluation index was verified. A method was proposed to evaluate the influences of on-board equipment such as converters on the floor vibrations of metro car floors in the workshops or the laboratories. Test results show that the evaluation method errors are about 10%. The method may guide the selection of main vibration components such as transformers, fans, etc., and avoid the emergence of large quantities of vibration faults.

Key words: on-board equipment, metro car floor, vibration, evaluation

摘要： 通过对某地铁车辆辅助变流器分别进行装车通电测试和车间台架通电测试，确定了导致车厢地板振动过大的原因，证明了当前车载设备振动评估指标的不合理性；在此基础上，提出了一种可在车间或实验室评估变流器等车载设备对地铁车厢地板振动影响的方法。试验测试结果表明，该评估方法误差在10%左右。该方法能够指导变压器、风机等车载设备的选型及避免大批量装车振动故障的出现，具有较高的工程应用价值。
