摘　　要：综合考虑悬架变形特点及车辆越障过程中的悬空现象,建立了无人地面车辆越障力学分析模型,对车辆通过凹坑过程进行了离散化处理,并进行仿真分析。结果表明,悬架刚度在车辆越障过程中起到了重要作用,为无人地面车辆越障性能研究及车辆设计工作提供了重要的理论依据。This research provides related methods and theory with the consideration of the characteristics of independent suspension system and the suspended phenomenon in the obstacle-crossing process.A mechanics analysis modelof tile unmanned ground vehicleduring obstacle crossing was established.The process of vehicle passing over pits was discretized and the simulation study was carried out.The results show that the vehicle suspension stiffness plays an important role in the process of the obstacle crossing. The paper provides an important theoretical basis for the obstacle-crossing performance study of unmanned ground vehicles and the design work of vehicles.
