摘　　要：提出了一种全地形,可实现轮-履快速转换的移动底盘设计方案,通过安装轮履复合变体式车轮(以下简称变体轮),可实现移动底盘在行驶过程中高机动性与高通过性相结合的目的,介绍了变体轮的工作机理,对移动底盘的驱动方案进行了选择,分析了机构越障过程中的动力输出特性,在此基础上利用多体系统动力学仿真软件RecurDyn建立了移动底盘车辆模型,并进行了越障能力仿真分析,为下一步的结构优化奠定了基础。A design scheme of an all-terrain rapid wheel track conversion mobile chassis was proposed. The installation of wheel-tracked variant wheel enabled the combination of high mobility and high passing ability in moving process of the mobile chassis. The working principle of the variant wheel was introduced. The driving scheme of the moving chassis was selected and the dynamic output characteristics was analyzed while passing through the obstacle. The mobile chassis vehicle model was established using multi-body system dynamics simulation software RecurDyn. The simulation of passing ability was performed, and the foundation for structural optimization was laid.
