| Abstract: | To quickly obtain the aluminum alloy alternative structural design of steel bonnet, the design method of topology optimization is introduced to finish the structural simulation calculation and design. Based on the steel bonnet inner plate structure, the multiple iteration optimizations are carried out in OptiStruct software by taking optimum conditions of the torsional rigidity ensuring and the mass ratio reducing, and then the corresponding aluminum alloy bonnet inner plate foundation structure is obtained. It can provide a reference for the subsequent design of the bonnet sheet metal. |
