摘　　要：对全地形车车架在复杂路况下的断裂、裂纹等现象进行研究,在Unigraphics软件中建立车架的数据模型,用通用数据格式parasolid将模型导入到ANSYS环境中,建立车架的有限元模型。用有限元理论分析静工况下全地形车架的强度特性,探讨了承载式车架不同部位的受力特性,并就车架薄弱位置提出结构改进方法,对全地形车进行改进前后的强度试验,验证该改进方法的合理性和可靠性。This paper researches premature failure data of ATV frame from complex driving tests and then builds a frame model of a vehicle by utilizing Unigraphics software. The frame model is translated into finite element model with ANSYS software, the static strength analysis on the frame is carried out based on finite element method, and the loading characteristics of the frame are investigated. This paper brings forward structure improvement methods based on weakness locations of frame. The strength tests on both modified and original framework are conducted, and the results verify the rationality and reliability of the design method
