【摘要】 稳健设计方法是近年来发展起来的一种工程设计方法,其指导思想是利用因素状况(原因)发生微小变差对因变量(结果)影响的不敏感性对产品的性能、质量和成本综合考虑做出最佳设计,以提高产品质量,降低成本。由此可见稳健设计的实质是一种优化问题,故本文将稳健设计亦称为稳健优化设计。随着计算机技术、优化和CAD技术的发展与应用,稳健设计方法在我国也得到了长足的发展。特别是在将稳健性应用于产品的优化设计方面的研究也越来越多。但是当前在如何将设计方法与应用软件相结合以实现快速设计方面的研究还是比较少见,有关科学计算软件MATLAB在稳健设计方法中的应用研究据笔者查阅的资料来看这方面的研究也很少。因此笔者试图尝试在这方面作一些探索性的工作。本文是在结合近年来工程稳健设计的发展及前人研究成果的基础上,总结了稳健设计的研究现状和发展趋势,将当前比较流行的大型科学计算软件——MATLAB引入到稳健优化设计方法当中,试图将二者结合起来,以达到使优秀的设计方法与先进的计算技术之间互相取长补短的目的。本文首次使用MATLAB优化工具箱对齿轮传动问题进行稳健优化设计求解,并给出了相应的算法程序。计算实例及设计结果表明该方法设计方便可行,避免了常规求解过程中繁杂的工程算法语言编程,既节省了时间又提高了效率,而且结果稳健可靠。更多还原

【Abstract】 The robust design method is a kind of engineering design method which developed in recent years, the guidelines are the use of the situation when factors (causes) change in a small scale as a result of modest deterioration variables (results) do not affect the sensitivity of product performance, quality and cost make the best integrated into the design to improve product quality and reduce costs. Therefore the essence of the robust design is an optimization problem.With the development and application of the computer technology, optimizes and the CAD technology, the robust design method has also been considerable development in our country. Especially the research on the applying robustness on the optimization design of the products is more and more. But at present how to combine the design method with application software in order to realize the rapid design research is still relatively rare, according to the materials that author have looked up to the application of a scientific calculating software MATLAB on robust design methodology is rarely available. So the author attempts to do some exploration work in this respect.This text is on the basis of combining the development of engineering robust design in the recent years, having summarized the research situation and development trend of the robust design, having introduced MATLAB which is the large scale scientific calculation software and relatively prevail at present to robust optimizing design method, attempts to combine the two together, in order to achieve the goal of learning from other’s strong points to offset one’s weaknesses each other between the outstanding design method and advanced computing technology.The text uses MATLAB optimization toolbox for solving the problem of robust optimization design of the gear wheel transmission for the first time, and gives the corresponding algorithm procedures. Examples and results show that the method is convenient and feasible, prevents multifarious engineering algorithmic language programming during the routine calculation procedure, having save time as well as raised the efficiency, and the result is robustly reliable.更多还原
