摘要
根据救援车辆行驶系统相关结构参数,对三角履带受力进行了分析,在此基础上,利用多体动力学软件Recurdyn中Track-HM模块建立了相应的多体动力学模型,通过改变车辆行驶速度、预张紧力、路面等影响履带张紧力变化的因素,进行多组仿真计算,得到不同工况下履带在运动循环周期内的受力规律。对比仿真结果可知行驶速度的提高使履带张紧力小幅度增加,预张紧力的增大使张紧力增大,上坡及障碍路面导致的冲击作用会使履带张紧力出现较大的峰值,因此应基于履带受力最大的工况,即最大爬坡度工况的履带载荷进行履带设计。
According to the structural parameters of rescue vehicle driving system,the force of the trianglar crawler was analyzed,on this basis,the corresponding multi-body dynamics model was established by using the Track-HM module in the multi-body dynamics software Recurdyn.By changing the vehicle speed,pre-tensioning force,road surface which affect the crawler tension force,multiple sets of simulation calculations were performed to obtain the force of the crawler during the motion cycle under different working conditions.Comparing the simulation results,it can be seen that the improvement of speed and pre-tension could increase the moving tension force.Moreover,the impact attributed to the uphill and obstacle roads could cause the crawler tension to be much greater than the average tension.Therefore,the design of the crawler should be based on the maximum crawler load,that is,the crawler load of the maximum climbing condition.
