摘　　要：为了分析高速磁浮列车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204自由度的横向动力学模型,施加轨道方向不平顺激励,研究了行驶速度、轨道不平顺以及弹性阻尼元件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,在不同车速下横向Sperling指标的变化趋势接近,都存在近似的敏感波长范围。并且随方向不平顺幅值的增大,横向Sperling指标非线性上升。横向两侧橡胶簧对车辆横向平稳性的贡献最大。In order to analyze influences of various factors in the process of vehicle straight driving, a lateral dynamics model of 204-DOFs was established based on multi-body dynamics software Simpack. After applying excitation of track lateral irregularity, the influence of speed, irregularity wavelength and amplitude, stiffness and damping components parameters on ride quality was studied. The simulation results in whole speed range of high-speed maglev vehicle shows that, when wavelenth changes, different speed corresponds to similar tendency of Sperling index, which has approximate range of sensitive wavelength. Besides, as the lateral irregularity amplitude increases, lateral Sperling index rises nonlinearly. Among stiffness and damping elements, lateral rubber springs has greatest contribution to the ride quality.
