| 摘 要： | 以某型号高速水稻插秧机车架为研究对象,利用三维建模软件UG对其参数化建模,并导入有限元分析软件ANSYS Workbench中对水稻插秧机车架进行有限元分析。该文进行了车架的应力计算,并对主要变形部位进行应力试验测量,将计算结果与田间试验数据进行对比,验证了有限元计算的正确性。以有限元分析结果为依据,建立了车架优化设计模型,通过计算提出较为合理的车架轻量化设计方案,经优化及结构改进,车架质量降幅达16.77%,证明了该优化方案的经济性和可行性。

| Abstract: | A type of high-speed rice transplanter frame was studied in the paper, and the three-dimensional modeling software UG was used for its parametric modeling, then the model was imported to FEA software ANSYS Workbench to analysis the frame. Different experimental conditions were simulated to calculate stress and deformation of the frame, and the stress of the main deformed part was measured. Then the calculated results were compared with experimental data, and the correctness of FEM results was verified. Based on the results of FEA, a frame model of optimal design was established, and one more reasonable lightweight design proposal was made by calculating. Through the optimization and improvement, the weight of the frame decreased by 16.77%, which showed the optimization program was economical and feasibility. |
