摘　　要：针对液压马达四轮驱动的动力方式,设计了轮履复合式救援工程机械底盘的车桥,对其在各行驶工况下的受力情况进行有限元分析和优化,并对优化的结构进行了模态分析。结果表明,该车桥结构在满足强度要求的基础上有良好的抗振性。A chassis axle for wheel/crawler rescue engineering machinery is designed against the drive power mode of FWD hydraulic motor. Finite element analysis of the driving force under each working condition is performed for optimization, and the optimized structure is verified by modal analysis. The results show that the axle structure can satisfy the strength requirement while presenting sound vibration resistance.

关 键 词：轮履复合 车桥 有限元 模态分析
