【Abstract】 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.更多还原
