摘　　要：针对某履带车托带轮受力过大导致相关结构损坏的故障现象,利用Recur Dyn建立履带行动系统动力学模型,通过测试和有限元计算获取行动系统主要部件特性参数并输入到模型,仿真分析了托带轮附座受力及上支履带的振动状态.对托带轮的布置进行了优化,使托带轮附座的受力有效降低,履带拍打翼子板的频次大幅减少.样车试验结果表明,优化改进措施有效,样车最终通过耐久性验证.Aiming at the failure phenomenon of the related structure damage caused by the overloading of support roller of a certain high speed tracked vehicle,a study on the Dynamic Model of the Track Action System Based on RecurDyn software was made.The characteristic parameters of the main components of the action system were obtained and input to the model by testing and finite element calculation.The stress on the pedestal of the bracket and the vibration state of the upper supporting track were analyzed by simulation.In this paper,the arrangement of the belt wheel is optimized.In this way,the force of the pedestal of the bracket can be reduced effectively,and the frequency of caterpillar flapping on the fender will be greatly reduced.The verification of real vehicle proves that the optimization and improvement are effective.The prototype finally passed the durability test.
