Abstract:

Targeting at realizing reliability-based robust optimization design of a multi-objective optimization, the additional items of sensitivity were generated via analysing of objective functions and constraints. And a model of reliability robust-optimization design was proposed based on the additional items of sensitivity. The impact degree of design variables on design objectives was determined by using the orthogonal experiment and variance analysis that were based on the axiomatic design. Design parameters were classified into groups by the uncoupled or decoupled optimization design that can make the optimization problems of multiple objective into single objective and can avoid the trade-off between design objectives. With the augmented multiplier method,reliability-based robust optimization design of caliper disc braker can be proceeded by using the software of symbolic toolbox and optimization toolbox of MATLAB. The numerical example shows that the proposed approach has higher precision and reliability.
