Abstract：An optimum design method of the double wishbone independent suspension based on the multidisciplinary design optimization ( MDO ) is presented .By taking the double wishbone independent suspension of a car model as the research subject , the multi-objective optimization functions of the minimum caster ,camber and toe angle change is constructed and the multidisciplinary design optimization is made based on the integrated ISIGHT and ADAMS /CAR software .The optimization results show that the optimized caster angle decreases by 2°correspondingly,and the range of camber and toe angles decreases by 0.45°and 0.5° respectively .The experiments verify that the steering portability and overall performance of suspension are improved.
