Abstract EN
This paper presents a parametric level set-based method (PLSM) for multimaterial topology optimization of heat conduction structures with volume constraints.
A parametric level set-based optimization model of heat conduction structures is built with multimaterial level set (MM-LS) model, which describes the boundaries of different materials by the combination of all level set functions.
The heat dissipation efficiency which means the quadratic temperature gradient is conducted as the objective function.
The adjoint method is utilized to calculate the sensitivities of the objective function with respect to expansion coefficients of the compactly supported radial basis functions (CSRBFs).
The optimal configuration is achieved by updating the expansion coefficients gradually with the method of moving asymptotes (MMA).
Several numerical examples are discussed to demonstrate effectiveness of the proposed method for multimaterial topology optimization of heat conduction structures.
