摘要
建立了考虑沉浮、点头、侧滚多方向振动的悬浮架垂向动力学模型,编制了系统动力学仿真程序,分析了某新型中低速磁浮悬浮架的振动动态特性;进一步研究了悬浮架结构解耦,特别是磁浮车辆特有的左右模块之间弹性约束的影响,为磁浮车辆抗侧滚悬挂参数设计提供依据。
Based on the viberation of bouncing,pitching and rolling directions,the vertical dynamics model of levitation chassis was established,and the equations of motion of the model were derived.A simulation program was designed to simulate the vibration dynamic characteristics of the levitation chassis for a certain latest middle and low speed maglev vehicle.The structure decoupling function of levitation chassis was further studied,especially the influence of elastic constraints between the maglev vehicle specific left and right module,and evidences were provided for designing the restraint parameters of module rolling.
