摘要: 在现代设计方法中，优化设计技术已经得到了广泛的应用，不管是在工程设计和应用，还是社会经济现象以及人民日常生活中，都可以找到优化设计的影子，都有学者在研究。而优化设计技术在机械设计方面的应用尤其广泛，有结构参数优化和机械结构优化等方面。很多的优化方面的软件也已经由各大高等院校和企业研究机构开发出来，并且在实际中得到了很好的利用。本课题吸取了前人的工作和经验，编写了一个简单的，易操作，可视化的软件。考虑到MATLAB在科学计算和矩阵计算等方面的强大功能，用MATLAB编写各算法的程序具有可读性强，简单等特点，结合VB来编写界面程序。本软件编写了无约束一维，无约束二维和有约束二维等算法。
关键字: 优化设计；MATLAB；VB；混合编程；无约束优化；有约束优化

Abstract: In modern design method, the technique of optimization design have already got the extensive application. Not only in the engineering design and apply ,but also in social economic phenomenon and people's daily life, we can find out the shadow of optimization design and have the scholar at study . The application of optimization design in the machine design aspect is particularly extensive. For example, the structure parameter optimization and the machine structure optimization and so on. A lot of software of the aspect have already been developed by the high etc. college and business enterprise research organization, and get the good application in physically. We summary the elder generation’s work and experiences ,then wrote a simple and operate easily software that can see to turn. In consideration of the MATLAB has the strong function in the aspect of science computes and matrix computes we wrote the procedure with the MATLAB. The procedure has the advantage of the strong readability and simplify etc. we write the interface procedure with the VB. This software includes one dimension and two dimension’s abandoned optimization and promissory optimization.
Keywords: optimization design ；MATLAB；VB；hybrid-programming
abandoned optimization；promissory optimization
