Combining the optimal design theory with robust design

the aggregation optimal robust design for automobile’s change speed gearbox is discussed.Based on optimizing the single objective

the least volume and the lowest noise as the objective

the multiple-objective and multiple-attribute of the gearbox are modeled using aggregation robust optimal design

and the aggregation robust design is described as a multiple-objection optimization.According to the result

the approach proposed is a practical robust optimal design method.
