基于产品功能分析与结构优化的机械设计方法

A Mechanical Design Method Based Product Function Analysis and Structure Optimization

在对机械产品功能和结构分析的基础上,建立了一种机械设计的分析和评价方法。该方法首先对产品进行功能分析和分解,形成若干产品子功能,在对子功能的实现机构进行分析和比较的基础上,应用功能—机构优化算法对产品的机构选择方案进行评价。通过对所选机构的结构组成进行分析和优化,形成最终的产品实现方案。最后,通过实例验证了该设计方法的可行性。

Based on the analysis of structure and function of mechanical products, the article establishes an analysis and evaluation method of mechanical design. In this method, product’s function is analyzed and decomposed into several sub-functions. On the basis of analysis and comparison of implement mechanisms, a function -mechanism optimization algorithm is established to evaluate the product’s mechanism composition program. Through analyzing and optimizing the structure of these mechanisms chosen in the product/s mechanism composition program, a final product implementation program is formed. Finally, an example is showed to demonstrate the feasibility of the design method.
