摘要:
针对永磁悬浮车辆，考虑永磁悬浮力、横向力、柔性轮胎及摩擦力特性对整车的影响，通过A级路面不平顺谱建立了车辆轮胎轨道耦合动力学模型，利用仿真软件分析了几种不同特性的轮胎对车辆振动的影响。结果表明：永磁悬浮车辆整车的振动是一个复杂的运动，柔性轮胎及摩擦力能有效减小振动，轮胎的弹性模量对垂直浮沉振动影响小，对横向偏移振动有一定的影响。
Abstracts:
Considered the influence of permanent magnetic suspended force, horizontal force, flexible tire and friction on the whole permanent magnet suspension vehicle, a vehicle-tire-track coupling dynamics model is established through the A-grade pavement irregularity spectrum, and the influence of tires with different properties on train vibration is also analyzed by using the simulation software. The result shows that the vibration of permanent magnetic suspended train is a complex motion; the flexible tire and friction can decrease the vibration effectively, but the modulus of tire elasticity has less effect on the vertical vibration than on the horizontal vibration.
