摘要

客运列车的乘坐舒适性是一个引人入胜的研究课题，多年来不断研究和改进，帮助我们实现了令人难以置信的速度。以菲亚特转向架Linke Hofmann Busch (LHB)客车为原型，建立了一个50自由度的刚性多体系统，对直线轨道进行了动力学分析。采用平均舒适标准法对不同车厢底板位置的乘客乘坐舒适性进行了评价。美国六级轨道频谱只在左侧轨道上引入，这对车辆起随机激励作用。在200-350公里/小时的速度范围内，对不同底盘位置的加速功率谱密度(PSD)和平均舒适度(Nmv)进行了比较。在车厢底板的左右位置观测到了Nmv指数和加速度PSD的峰值。

Simulation-based analysis of passenger ride comfort under different track conditions

The ride comfort of a passenger train is a fascinating research topic, continuously investigated and improved over the years, helping us to achieve unbelievable speeds. A rigid multibody system with 50 DOF, depicting the actual Linke Hofmann Busch (LHB) coach with FIAT bogie, is created to carry out the dynamic analysis on the straight rail track. The mean comfort standard method has been used to assess passenger ride comfort at different rail-car floor locations. The American sixth grade track spectrum has been introduced on the left rail only, which acts as a random excitation to the vehicle. Power spectral density (PSD) of acceleration and mean comfort index (Nmv) have been compared at different car floor locations for a speed range of 200-350 kmph. The peak values of the Nmv index and PSD of acceleration have been observed at the left and right locations of the rail-car floor.
