摘　　要：针对曲柄滑块机构运动精度设计问题,提出了一种多元相关质量特性的稳健设计方法,不仅可以计算多元质量损失,还能够处理质量特性之间的相关性。以二元相关质量特性稳健设计问题为例,建立相应的优化设计模型,计算结果表明所提供的方法更能客观地反映由随机因素引起的产品质量损失,能够进一步提高曲柄滑块机构的设计质量与稳健性。Aiming at Motion precision design of slider - crank mechanism, a robust design method for multivariate related quality characteristics was proposed. It can not only calculate the multiple mass loss, but also deal with the correlation a- mong the quality characteristics. Taking the robust design of binary related quality characteristics as an example, the corre- sponding optimal design model was established. The calculation results show that the proposed method can objectively reflect the loss of product quality caused by random factors,improve the design quality and robustness of the slider - crank mecha- nism further.
