Abstract: Aiming at the problem of difficult transportation of materials on non-structural complex pavement, a six- wheeled vehicle with folding and swinging arm function was designed. This special structure effectively improved the obstacle-surmounting performance of vehicles. On the basis of the theoretical analysis of the crossing vertical obstacle ability of the six wheel vehicle, Recurdyn software was used to simulate and the reasonableness of the results was verified through real vehicle experiments. The results were analyzed to provide a basis for further structural optimization and control system design of six-wheeled vehicle.

摘要： 针对非结构复杂路面运输物资困难的问题，研究设计了具有折腰和摆臂功能的6轮车，这种特殊结构有效提升了车辆的越障性能。在 对6轮车越垂直障碍高度能力进行理论分析基础上，利用Recurdyn软件进行仿真，再通过实车实验验证结果合理性，并对结果进行分析，为6 轮车进一步结构优化及控制系统设计提供依据。
