摘 要

本文主要讨论关于折叠桌的参数化设计问题，在任意给定桌面高度和桌面半径参数时，通过数学建模建立数学模型给出算法，确定所需平板材料尺寸以及最优的加工参数。

Solidworks作为目前最受欢迎的三维机械设计软件之一，在机械制造行业一直起着至关重要的作用。但为了缩短产品生产周期，提高生产效率，有必要对solidworks进行二次开发。本文介绍了折叠桌参数化设计的软件开发过程，基于VB编程语言，对开发人员具有一定参考意义。

Abstract

In this paper, we discuss the parametric design problem of folding table. When the height of any given table and the radius of the table are given, the mathematical model is established by mathematical modeling to determine the required plate material size and the optimal machining parameters.

Solidworks, as one of the most popular three-dimensional mechanical design software, has played a vital role in the machinery manufacturing industry. But in order to shorten the product production cycle, improve production efficiency, it is necessary for secondary development of solidworks. This paper introduces the software development process of parameterized design of folding table, which is based on VB programming language and has certain reference significance for developers.
