摘　　要：全地形救援装备行驶工况复杂,导向轮连接轴的强度对其行走系统至关重要。针对某全地形救援装备导向轮连接轴断裂问题,建立力学模型,进行有限元仿真分析,判断断裂原因,并提出优化方案,对优化后的连接轴进行有限元仿真分析,验证其可行性。结果表明,导向轮连接轴断裂由静强度不足引起;优化后导向轮连接轴所承受最大应力大幅下降,满足静强度要求,能够保证全地形救援装备正常行驶。The travelling conditions of all-terrain rescue equipment are complicated,and the strength of the guide wheel coupling axle is crucial to its travelling system.In view of the fracture problem of the guide wheel coupling axle of the all-terrain rescue equipment,a mechanical model is established,finite element simulation analysis is carried out to determine the cause for the fracture,an optimization plan is proposed,and finite element simulation analysis is carried out on the optimized coupling axle to verify its feasibility.The results show that,the fracture of the guide wheel coupling axle is caused by insufficient static strength,and the maximum stress on the guide wheel coupling axle after optimization is greatly reduced,which meets the static strength requirements and can ensure the normal travelling of the all-terrain rescue equipment.
