Abstract:

Based on the topological optimization and layered decision-making theory of multi-objective optimization, a new methodology of multi-objective topological optimization design (MOTOD) was proposed, and the method was applied in the optimization design of structures in the key unit of ultra-precision stages. The simulation results based on ANSYS prove that MOTOD significantly improve the static characteristics, dynamic characteristics and the design efficiency of multi-objective structure optimization design, satisfies the rigorous requirements in performance of ultra-precision structures, and provides a theoretical guide and method for modern structure design and improvement.
