摘　　要：为了优化柠条收割机中间变速箱壳体的结构参数,提高其结构强度和刚度,保证壳体不被破坏,采用ANSYS软件对其进行了有限元分析。根据壳体的结构和受力特点,建立了有限元模型,分别给出了在静止和工作工况下的载荷和边界约束条件,选用Solid95实体单元进行分析和计算,得到了不同工况下结构的位移和应力变化规律,结构危险点的最大应力和应变分别为24.9MPa和0.129mm。结果表明,变速箱壳体结构能够满足强度和刚度的要求,有优化的空间。因此,利用ANSYS有限元软件对变速箱壳体进行静力学分析,可作为今后壳体结构设计和改进和一种可行方法。In order to optimize the structural parameter, to enhance its structural strength and rigidity, and to ensure the gear-housing is not destroyed, the frame is simulated by ANSYS for the caragana microphylla gear-housing. According to its structure and mechanical characteristics, the model is established. The loads and constraints are given by the self weight and loads respectively. Using the solid95 element to analyzed the composition, the displacement and stress distri- bution value are obtained. The maximum stress of structural danger point is 256 and the values achieve 24.9Mpa and the maximum deformation of structural danger point is 6752 and the value is 0. 129ram. The result indicated that gear- housing made by the material of cast iron is available. So, it is available to analysis statistic of the structure of the gear -housing with the ANASYS.
