- Abstract:
- Large-scale box parts are widely used in mechanical equipment. They are mainly designed based on traditional experience, and the structure is bulky. Using the SIMP variable density method, with the goal of minimizing compliance and volume as constraints, the topology optimization of large-scale box parts is established. Mathematical model. Using density filtering and gray filtering to solve the problem of numerical instability in the process of topology optimization. Using the OC criterion to solve the topology structure under different load conditions, and obtaining the new structure of large box parts through structural synthesis, and using finite The feasibility and practicability of the structure are verified by the meta-method, which provides a useful guidance for the structural design of large box parts.
