摘要: 为了分析高速磁浮列车直线行驶过程中各项因素的影响，基于多体动力学软件Simpack建立了高速磁浮列车的垂向动力学模型，施加轨道谐波高低不平顺激励，研究了行驶速度、轨道不平顺波长和幅值、车重和悬浮架重以及一二系悬挂参数对于平稳性的影响。对全高速域的仿真结果表明：该型高速磁浮列车满载通过直线线路时，不同车速对应于不同的敏感波长范围。随着列车速度的增加，引起车体主频响应的波长增长，敏感波长范围扩大。并且随高低不平顺幅值的增大，垂向Sperling指标非线性上升，且上升速率逐渐减小。另外，车体重量的增加，悬浮架重的减小，会改善平稳性。在高速磁浮列车的工程应用参数范围内，适当减小一系悬挂刚度、二系悬挂刚度和阻尼，增大一系悬挂阻尼，有助于改善平稳性。其中二系悬挂对车辆平稳性的贡献最大。Abstract: In order to analyze influences of various factors on ride quality in the process of vehicle straight driving, a vertical dynamics model of high speed maglev vehicle was established based on multi-body dynamics software Simpack. After applying excitation of track harmonic irregularity, the influence of speed, irregularity wavelength and amplitude, weight of carbody and levitation bogies, suspension parameters on ride quality was studied. The simulation results in whole speed range of high speed maglev vehicle show that, different speed corresponds to different range of sensitive wavelength; with the increase of speed, the wavelength causing the dominant frequency of carbody grows, and range of sensitive wavelength expands. Besides, as the vertical irregularity amplitude increases, the vertical Sperling index rises nonlinearly, while its rising rate decreases gradually. What′s more, increasing weight of carbody and decreasing weight of levitation bogies will improve the ride quality. Furthermore, within the range of engineering application parameters, appropriately reducing primary/secondary vertical stiffness and secondary vertical damping, as well as increasing primary vertical damping, can help to improve the ride quality. Among them, the secondary suspension has greatest contribution to the ride quality.
