摘要

文章针对磁浮与轮轨列车在车载设备振动环境方面存在的显著差异，为解决磁浮设备加速振动试验的问题，基于商用磁浮3.0版列车在同济大学高速磁浮试验线进行了整车振动测试，采用统计容差法归纳得到实测功率密度谱（PSD），推导出的加速因子为5.66，以此设计了磁浮设备垂向、横向和纵向的加速振动试验剖面。经对实测PSD和IEC 61373:2010标准PSD分析可知，实测PSD在2~50 Hz频段内的量级低于标准谱，两者加速度均方根值（RMS）的相对偏差为-35.3%～-59.4%；实测振动频率上限为500 Hz，高于标准频率上限150 Hz。由此可知，磁浮设备的振动量级低于轮轨列车，振动频带范围高于标准要求，采用实测PSD可更真实地模拟磁浮列车现场运行振动环境。

Abstract

In view of the significant difference between maglev train and wheel-rail train on the vibration environment of on-board equipment

for the accelerated vibration test of maglev equipment

the whole vehicle vibration test of commercial maglev version 3.0 train was carried out on the high-speed maglev test line of Tongji University. According to the measured PSD obtained by the statistical tolerance method

the acceleration factor was deduced to be 5.66. Based on this

the accelerated vibration test profiles in

and

directions of the maglev equipment were designed. The comparison between the measured PSD and the standard PSD in IEC 61373:2010 shows that the magnitude of the measured PSD is lower than that of the standard PSD in the frequency band of 2~50 Hz

the relative deviation of the RMS values between the two is -35.3% to -59.4%

the upper limit of vibration frequency of the measured PSD is 500 Hz

higher than that of the standard PSD

which is 150 Hz. It can be seen that the magnitude of vibration of maglev equipment is lower than that of wheel-rail train

but with a wider vibration frequency band range than standard requirement. Therefore

using the measured PSD can more truly simulate the operating vibration environment of maglev equipment.
