摘要
列车车轮多边形磨耗问题是目前高速列车运行过程中普遍存在的,多边形的出现会加剧轮轨间的相互作用,引发显著的异常振动噪声问题。通过跟踪测试车轮多边形发展和转向架区域振动噪声,分析讨论高阶车轮多边形磨耗对高速列车转向架区域噪声的影响。研究表明,当轮轨表出现显著多边形时,转向架区域噪声的显著频率会变为与多边形和行车速度相关的频率范围,随着车轮多边形磨耗水平的增加,转向架区域噪声显著增大。当车轮多边形磨耗激励频率和车辆过轨跨频率发生信号调制时,还会产生谐频噪声问题,使车轮多边形对噪声的影响频率范围增大,研究成果可以为车辆振动噪声控制提供依据和参考。
The polygonal wear of wheels of high-speed trains is a common problem,and it will increase the wheel/rail interaction and cause the abnormal vibration and noise problem.In this paper,the tracking test of polygonal wear and noise of bogie area was conducted to study the effect of high-order wheel polygon wear on the noise.The results show that when the polygonal wear is serious,the dominant frequency range in the bogie area is associated with the polygonal order and running speed.With the increasing of the polygonal wear,the noise of bogie area increases significantly.When the signal modulation happens between the wheel polygon wear excitation signal and the vehicle across-the-sleeper signal,the harmonic frequency of noise signal will occur and it will enlarge the frequency band of the polygonal wear excitation.The research results may provide a basis and a reference for vehicle vibration and noise control of vehicles.
