Abstract

The invention belongs to the related technical field of material structure optimization, and discloses a dynamic integrated design method for multiple porous material structures. The method comprisesthe following steps of (1) carrying out initialization partitioning on a macrostructure design domain of a to-be-designed material structure to form subareas of a macrostructure, and enabling different subareas to be formed by periodically arranging multiple porous material microstructures with different functions; (2) aiming at the macrostructure and the microstructure, constructing a dynamic integrated design model oriented to multiple porous material structures, determining equivalent material attributes of the microstructure in the macroscopic partition, and further obtaining a macroscopicdisplacement field of the macrostructure; and then, based on the macro displacement field, solving an objective function of the dynamic integrated design model, determining design sensitivity, updating macro design variables and micro design variables, and further determining the optimal macro structure and micro structure. According to the method, the calculation cost and the material design variable are reduced, and the structural performance is improved.

Description

technical field [0001] The invention belongs to the related technical field of structural optimization design, and more specifically relates to a dynamic integrated design method for multiple porous material structures. Background technique [0002] The design of mechanical structures includes the construction of macrostructures and the design of local materials; for the construction of macrostructures, it is necessary to seek a reasonable distribution of materials in the structural design domain and achieve the optimal performance of macrostructures under given constraints. Purpose. The local material design is to change the macroscopic equivalent properties of the material by changing the microstructure of the material, and then optimize the product performance. In the construction of the macrostructure, local material elastic properties need to be considered, while in the traditional mechanical structure design, the value of this material elastic property is set to a fix...
