摘要:
大型箱体零件在机械设备中使用广泛,主要依靠传统经验设计而成,结构笨重.采用SIMP变密度法,以柔顺度最小化为目标,体积为约束,建立了大型箱体零件结构的拓扑优化数学模型.利用密度过滤和灰度过滤处理,解决了拓扑优化过程中数值不稳定问题.使用OC准则求解获得不同载荷工况下的拓扑结构,通过结构综合获得大型箱体零件新型结构,并用有限元方法验证该结构的可行性和实用性,为大型箱体零件的结构设计提供了一种有益的指导.
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.
