For the purpose of energy saving and emission reduction, lightweight design is carried out for balanced suspension bracket. Using the method named DFMA ( Design for Manufacturing and Assembly), with the aid of casting simulation tool MAGMA, structure optimization tool OPTISTRUCT and topology optimization tool ABAQUS, the final product is lightened by 40%, safety factor of which is increased by 25%, and cost is reduced by 5%. Data from bench test of proves feasibility of the lightweight design plan, meanwhile the product quality is improved and development time is shortened.
