摘要随着科学技术的发展与机械设计水平的不断提高,人们对机械结构性能、成本、可靠性等要求越来越高,因此优化范围和优化难度也越来越高。传统的优化方法有时候难以满足要求,为了适应优现在设计的需求智能算法(如神经网络算法)应运而生。MATLAB是由美国Mathworks公司开发的在各种场合均可运用的软件,它不仅编程简单,参数设置方便。而且集成了几乎所有传统优化和智能算法的工具箱,为设计人员提供了极大的方便。50221
本文先通过MATLAB编程完成神经网络样本采集,然后创建并训练神经网络,再利用优化工具箱来实现相对复杂的实际工程项目的优化,最后通过工程软件Pro/e进行仿真分析,得到了相对不错的优化结果,对工程实际设计具有重要的参考价值。

Abstract With the continuous development of science and technology ,and the higher requirement is raised on the structural property, cost and reliability of mechanics, the optimal range and optimal difficulty become more difficult. Traditional optimization methods sometimes can not satisfied the requirements of the design. In order to meet the needs of the modern design,The intelligent algorithm (such as neural network algorithm) came into being.MATLAB a software developed by Mathworks,a company of United States,which can be used on various occasions. It is not only easiy to program, convenient to set parameter, but also integrate almost all the toolbox of traditional and intelligent optimization
algorithm , providing a great convenience to the designers.
In this article,I will,firstly, describe how to get the sample of neural network through MATLAB programming , secondly ,create and train the neural network, thirdly ,use optimization toolbox to achieve the optimization of practical projects, and finally use engineering software,Pro / e,complete simulation analysis to test and verify the results.It can be a important reference to the actual design of the project.
Keywords: intelligent algorithm sample collection neural network simulation analysis
