车辆与动力技术

基于某型越野车辆，提出一种轮履复合式变结构轮方案，并对该车辆越障性能进行研究.利用动力学原理，对变结构轮车辆通过壕沟和爬斜坡性能进行理论分析计算；在Adams软件中建立车辆仿真模型，并在壕沟、坡度情形下分别进行仿真分析.结果表明，变结构轮车辆仿真值与理论值基本一致，证明了理论分析的正确性；同时，也说明了变结构轮车辆具有良好的越障能力.这为变结构轮的进一步优化及应用奠定了良好基础.

Based on a off-road vehicle, a wheel-track composite reconfigurable wheel scheme was proposed, and the obstacle-crossing performance of the vehicle equipped with these wheels was investigated. Using dynamic principles, theoretical analyses and calculations were performed for the vehicle crossing trenches and climbing slopes. Simulation models were established in Adams software, and analyses were conducted under trench-crossing and slope-climbing conditions. The results show that simulation values agree well with theoretical values, validating the theoretical analysis and demonstrating the excellent obstacle-crossing capability of the reconfigurable wheel vehicle. This work provides a solid foundation for further optimization and application of the reconfigurable wheel.
