基于ANSYS的单级减速器箱体可靠性优化设计

Reliability Optimization Design of Single-Stage Gearbox Based on ANSYS

摘要: 齿轮减速器以效率高，可靠性高，工作寿命长，维护简单等特点而应用范围较广。箱体作为减速器的主要零件，在减速器的设计中占有重要的地位。由于箱体的设计裕度保守，造成了材料上的浪费，使结构更加笨重，同时也增加了成本。随着计算机技术和有限元分析方法的发展，利用有限元分析的方法对结构进行分析已成为产品设计中的一个重要环节。本文利用SolidWorks维建模技术，建立单机齿轮减速器箱体的三维模型，将箱体模型导入ANSYS Workbench中。通过对箱体进行静力学分析、模态分析、谐波响应分析以及基于筛选进行优化，可以对箱体的裕度保守区域进行优化，从而降低了减速器质量，可以提高减速器箱体的设计效率，降低设计费用，增加了效益，具有一定实用价值。

Abstract: Gear reducers are widely used for their high efficiency, high reliability, long working life and simple maintenance. The case, as the main part of the gear reducer, occupies an important position in the design of the gear reducer. Due to the conservative design margins of the case, it causes a waste of material, makes the structure bulkier, and also increases the cost. With the development of computer technology and finite element analysis methods, the use of finite element analysis methods to analyze the structure has become an important part of product design. In this paper, SolidWorks dimensional modeling technology is used to establish a three-dimensional model of the single gear reducer case, and the case model is imported into ANSYS Workbench. Through the static analysis of the case, modal analysis, harmonic response analysis and optimization based on screening, the case can be optimized for the margin conservative region, which reduces the quality of the gear reducer, and can improve the design efficiency of the gear reducer case, reduce the design cost, increase the benefits, and have some practical value.
