摘　　要：驱动轮系统是重型履带式全地形应急救援装备的关键部件,不仅要承受较大的履带张紧力,在车辆运行过程中还需承受来自地面的巨大冲击力,因此保证其安全运行是确保重型履带式全地形应急救援装备正常工作及保障乘客安全的关键。针对某重型履带式全地形救援装备的典型工作状况,分析其驱动轮系统的受力情况,根据理论计算推导驱动轮系统两侧螺栓连接部位承受的应力载荷,利用有限元分析法对减速器壳体进行仿真分析,结果表明,该款驱动轮系统结构设计合理,满足使用要求。所述的建模方法、分析结果均可为驱动轮系统的设计优化提供一定参考。The drive wheel system is a key component of heavy-duty tracked all-terrain emergency rescue equipment,which not only bears large track tension,but also bears huge impact force from the ground during vehicle travelling,so ensuring its safe operation is the key to ensuring the normal operation of the heavy-duty tracked all-terrain emergency rescue equipment and guaranteeing the safety of passengers.Based on typical working conditions of the heavy-duty tracked all-terrain rescue equipment,the force situation of its drive wheel system is analyzed,the stress load on the bolted parts on both sides of the drive wheel system is deduced according to the theoretical calculations,and finite element analysis method is used for simulation analysis of the reducer housing.The results show that,the structure of the drive wheel system is reasonably designed and meets the requirements for use.The described modelling method and analysis results can provide certain reference for the design optimization of the drive wheel system.
