Abstract EN
This paper investigates the structural design optimization to cover both the reliability and robustness under uncertainty in design variables.
The main objective is to improve the efficiency of the optimization process.
To address this problem, a hybrid reliability-based robust design optimization (RRDO) method is proposed.
Prior to the design optimization, the Sobol sensitivity analysis is used for selecting key design variables and providing response variance as well, resulting in significantly reduced computational complexity.
The single-loop algorithm is employed to guarantee the structural reliability, allowing fast optimization process.
In the case of robust design, the weighting factor balances the response performance and variance with respect to the uncertainty in design variables.
The main contribution of this paper is that the proposed method applies the RRDO strategy with the usage of global approximation and the Sobol sensitivity analysis, leading to the reduced computational cost.
A structural example is given to illustrate the performance of the proposed method.
