Problems solved by technology

[0003] However, in actual engineering, there are many load conditions of nodes, and the optimal solution under a single condition may be a non-optimal solution under other conditions.
In the process of node topology optimization, if the most unfavorable working conditions are not found from the multi-working conditions before solving, the obtained nodes will be only "suboptimal" nodes, which will affect the safety, economy and applicability of the nodes

Abstract

The invention discloses a multi-working-condition special-shaped node topological optimization design method based on an RBF (Radial Basic Function) agent model. TAccording to the method, an RBF agentmodel and a multi-island genetic algorithm are adopted to obtain the most unfavorable load working condition in multiple working conditions, and then an SIMP method is adopted to obtain a special-shaped node topological optimization result under the most unfavorable load working condition. According to the method, finite element software ABAQUS and multidisciplinary optimization software Ilight are integrated, and the advantages of all the software are brought into full play; an RBF agent model is adopted to effectively solve the problems of multiple design variables, large model calculationamount and the like.

Description

technical field [0001] The invention relates to a method for topology optimization design of special-shaped nodes, in particular to a method for topology optimization design of multi-working-condition special-shaped nodes based on an RBF agent model. Background technique [0002] In recent years, with the application and development of free-form structures, more and more special-shaped nodes have appeared in practical engineering. The geometric shape of special-shaped joints is irregular and the stress is complex. If the traditional joint design method is adopted, not only the design period is long, but also it is difficult to obtain optimal mechanical properties and minimum steel consumption. Therefore, topology optimization becomes an effective design method for special-shaped nodes. At present, scholars at home and abroad have conducted research on node topology optimization, mainly topology optimization under the action of a single working condition. [0003] However, ...
