Abstract：Based on the material property of ductile iron 800-5, the topological optimization of the balance axle bracket of heavy truck is carried out with finite element software to achieve the target of 20% lightweight of castings. With MAGMASOFT  software to carry on the preliminary process design and simulation to the heavy truck bracket, has found casting defect position. Based on these simulation result, optimization process design scheme has been done Trial has been carried on and compared with simulation result With the DOE function of the MAGMASOFT誖, the Chemical composition and chill dimension are optimized, and the optimal Chemical composition and the optimal chill dimension found out to realize bracket SOP smoothly.
