多轴轮式车辆通过连续障碍性能仿真研究

Study on the Performance of Multi-Axis Vehicle Crossing Continuous Obstacles

综合考虑了独立悬架系统行程特点及车辆越障过程中的悬空现象,建立了带独立悬架的多轴轮式车辆越障力学分析模型,对车辆通过连续越障的分析过程进行了离散化处理,并进行了仿真分析.得到了多轴车辆通过连续障碍过程中车身与地面干涉情况的定量结果,为多轴轮式车辆越障性能研究提供了理论依据.

This research provides related methods and theory with the consideration of the characteristics of independent suspension system and the suspended phenomenon in the process of crossing obstacle.A crossing obstacle mechanics analysis model of the multi-axis vehicle with independent suspension system was established.The process of vehicle crossing continuous obstacles was discretized and the simulation study on a multi-axis vehicle was carried out.The quantitative results of interference between vehicle body and the ground were obtained during the multi-axis vehicle crossing continuous obstacle.
