摘要
公差可行稳健设计对于提高产品的质量起着重要的作用。在公差可行稳健模型的基础上,提出基于两步法和直接优化法的公差可行稳健设计法,针对约束函数为线性函数和非线性函数,采用基于重点抽样方法(MPP)进行装配成功率的估算,实现了对公差可行稳健性的评价。最后用实例进行验证。
Tolerance feasibility robust design is very important to improve the product quality. Presents a method for tolerance feasibility robust design based on tolerance feasibility robust model. The most probable point based importance sampling method is used to evaluate assembly yield for linear and non-linear functions. Therefore, the evaluation of tolerance feasibility robust design is realized. Finally, an example is given to illustrate the validity of the proposed model. The resuh shows that the method is reasonable.
