【摘要】 利用多体动力学软件Recurdyn建立了某型履带车辆的整车非线性多体动力学模型,对该模型在标准路面(D,E,F级)上以不同车速行驶时,车体振动特性进行了动态仿真,对车辆的动态响应进行了分析,结果表明采用多体动力学模型仿真车辆平顺性可以达到较高的精度,而且这种方法可以用于车辆悬挂结构、性能设计中的参数选择,也可以为车辆悬挂的主动控制策略的研制提供了理论依据。更多还原

【Abstract】 A comprehensive nonlinear vehicle model of a tracked vehicle suspension system is established by using multi-body dynamics software Recurdyn. Dynamics vibration characters of the multi-body model is simulated,which is about the model on the different roads(such as D,E,F)by the different riding speeds,the results from dynamics simulation can be proved that using multi-body system simulation the vehicle ride comfort performance could be simulated accurately,that the appropriate parameters also could be selected in the structure and performance design about vehicle suspension,that the active suspension controlling strategy could be obtained.更多还原
