摘要
在建立橡胶轮转向架车辆系统动力学模型的基础上,研究了随机激扰对车辆系统振动特性的影响.结果表明,在随机激扰作用下,橡胶轮转向架车辆系统将产生激烈振动,且车辆运行速度越高,振动越剧烈,但轮重减载率始终维持较低的振动值.
The dynamical model for vehicle system with the rubber-tired bogie is established and the influence of stochastic excitation on vibration performance for vehicle system is investigated. The results show that the vehicle system with the rubber-tired bogie has intensive vibration when the stochastic excitation is applied, and the vehicle running speed is higher, the vibration is more intensive, but the off-load rate of wheels is always small.
