摘要
运用多体动力学仿真软件Recurdyn构建煤矿应急排水车单侧越障模型,进行单侧越障仿真分析,重点分析不同障碍高和不同运行速度对左右独立履带的驱动轮转矩的影响。仿真研究结果表明:随着障碍高度和运行速度的增加,驱动轮转矩呈非线性增加,且未超出设计临界最大转矩;越障瞬间由于左右独立履带产生的的转动能不同,会引起左右驱动轮转矩差值。通过对该样机的仿真分析为实车安全稳定运行和进一步优化提供可靠依据。
Multi-body dynamics simulation software Recurdyn is used on coal mine drainage emergency vehicles to construct unilateral obstacle model for simulation analysis,to study the effects of different barriers and different speed for independent crawler drive wheel torque.The simulation results show that,with the increase of barrier height and operating speed the driving wheel torque non-linear increases within the maximum critical torque 7k N · m.The different of rotational energy of independent track in instant obstacle,causes difference in driving wheel torque.This prototype simulation analysis provides a reliable basis for the safe and stable operation of actual vehicle and further optimization.
