According to the stuctural features of the die casting new-type magnesium alloy steering wheel for the Dongfeng commercial vehicles

the process optimization and the development of the components were conducted with the aid of casting CAE . The casting defects

such as crack

porosity

and formation origination were analyzed. Based on the analysis

casting structure and process were modified. By trial production and the performance testing of the magnesium alloy steering wheel

it was proved that the improvement of the process design and the structure of the casting were effective.
