    摘要:

    以某大豆收获机的车架为对象,利用三维建模软件Solidworks进行了参数化建模,导入有限元前处理软件Hypermesh对车架进行有限元网格划分和模态仿真分析,对车架样件进行模态试验分析,验证了仿真模型和结果的正确性。对车架不同工况下进行了强度校核计算;以车架固有频率和动载荷系数为2.5时材料的最大许用应力为约束,以车架质量最小为目标,进行了轻量化优化设计,优化后底盘车架减质量16%。

    Abstract:

    In this paper, the chassis frame of a soybean harvester is taken as an object. Using three-dimensional modeling software Solidworks for the parametric modeling and finite element before the import processing software Hypermesh for the finite element meshing and modal simulation analysis of the chassis frame the modal test of frame samples is conducted to verify the validity of the simulation results.The strength of the chassis under different working conditions is checked and calculated. With the maximum allowable stress of the material taken as constraint when the natural frequency and dynamic load coefficient of the chassis are 2.5, and with the minimum weight of the frame taken as the target, the lightweight optimization design is carried out and the mass of the chassis after optimization is reduced by 16%.
