为降低除草机车架质量和整机油耗,提高作业性能,采用三维建模软件Autodesk Inventor对其进行参数化建模,并导入ANSYS Workbench中。依据不同的工况对其进行有限元静力学分析,并设计了车架应力试验,用试验结果检验仿真结果的正确性。基于静力学有限元分析结果,采用拓扑优化与尺寸优化的两级优化方案对车架进行轻量化设计,并提出了车架结构的改进方案。研究结果显示:两种工况均满足强度与刚度要求;仿真结果与试验结果基本吻合,验证了有限元模型的合理性;通过对车架的轻量化设计,使车架总质量降低了33.89%,实现了轻量化目标;根据轻量化结果对车架进行结构改进,改进后的车架应力分布得到改善,车架最...

In order to improve the operation performance of the mower by reducing the weight of the frame and the fuel consumption,it is necessary to carry out digital analysis in the following steps： parametric modeling design of mower frame with 3 D modeling software Autodesk Inventor; importing into ANSYS Workbench subsequently; and meshing,constraints adding and loading. The finite element static analysis was conducted on the frame according to the different working conditions. In order to ensure the accuracy of the finite element model,the frame str...
