Document Type and Number:
WIPO Patent Application WO/2024/050982
Kind Code:
A1
Abstract:
Disclosed are a method and apparatus for designing a cold conduction structure on the basis of topology optimization. The method comprises: establishing a lightweight model and a heat dissipation model, wherein the lightweight model is a lightweight topology optimization model for a cold conduction structure, and the heat dissipation model is a heat dissipation topology optimization model for the cold conduction structure; respectively determining an optimization condition for the lightweight model and an optimization condition for the heat dissipation model; and performing multi-objective thermo-mechanical coupling topology optimization on a multi-objective weighted optimization model obtained by weighting the lightweight model and the heat dissipation model, so as to obtain a topology configuration of the cold conduction structure that meets design indexes. The present solution realizes coupling optimization of a stress field and a temperature field by means of weighting a lightweight model and a heat dissipation model, thereby obtaining a configuration that simultaneously meets multiple physical field design indexes, and thus increasing the design efficiency.
