Abstract:
The topology optimization concept design of the structure is completed by the approximate simulation and optimizing parameter setting of an electromagnetic-propelling device with a moving large load. The dynamic loading problem of moving large load infinite element analysis is solved by the VDLOAD subprogram second development of Abaqus. The final structure performance of the electromagnetic-propelling device is optimized by the real-code genetic algorithm based on the stiffness equilibrium design method,the global optimization method including all key shapes and design variables and manual adjustments. The results show that the electromagnetic-propelling device meets its large load and high stiffness,the requirements of thrust stability and the equilibrium of the structural stiffness and light weight; the overall stiffness of the system is controlled within a certain limit.
