摘要：
In order to solve the uncertain factors in the design optimization of mechanical and electrical products, a robust design method for interval uncertainty was proposed based on sensitivity analysis. Firstly, discussed the Sobol' method of the sensitivity analysis theory, the factors which had great influences on the system were selected. Secondly, by using the characteristics of interval uncertainty factors and the effects of uncertain factors on the whole system were analyzed in a certain interval. Finally, a robust design optimization model for interval uncertainty was given based on sensitivity analysis. The effectiveness of the proposed method was proved by an engineering examples. © 2019, China Mechanical Engineering Magazine Office. All right reserved.
