STRUCTURAL TOPOLOGY OPTIMIZATION DESIGN FOR HEAT CONDUCTION

摘要

Based on topology optimization techniques of structural mechanics, an effective method for solving the structural design problems of heat transfer is presented. The topology optimization model of heat conduction is then constructed and the corresponding Optimization Criteria based on density approach is derived to solve the optimal material distribution of heat conduction field. A Filtering technique is employed in density field to eliminate numerical instabilities in the process of topology optimization. Numerical examples are presented to demonstrate the validity and the applicability of the proposed method, with the results laying a reliable foundation for the subsequent shape and size optimizations in thermal engineering applications.
