Technology Overview of Finite Element Analysis and Optimization

该文介绍了有限元分析技术在工程中的应用以及利用有限元优化软件ANSYS的优化设计方法,针对小型甘蔗收获机刀盘齿轮箱箱体轻量化设计的问题,分别利用零阶法和一阶法对箱体结构进行优化计算,从而计算出最优解,即箱体前后板厚为5 mm、左右板厚为5 mm、底板厚度为20 mm,为小型甘蔗收获机整机的轻量化设计提供参考。

This paper introduces the application of finite element analysis in engineering and optimization design methods using the finite element optimization software ANSYS. Aimed at the problem of lightweight design of small sugarcane harvester cutter gearbox, respectively using the methods of zero-order and first-order, optimization calculation of enclosure structure of gearbox is carried out, and the optimal solution is calculated, namely the front and rear thickness is 5mm, the left and right thickness is 5mm, the thickness of bottom plate is 20mm. This paper can provide a reference for lightweight design of small sugarcane harvester.
