Some key problems of topology optimization about thermo-structural coupling field are studied. The governing equations and optimization model are deduced, and an adjoint method is used to calculate the sensitivity of structure＇s response. The optimizer used for topology optimization of coupling structure is researched and a flow chart of topology optimization about coupling analysis is presented. The corresponding algorithms are realized with numerical methods and verified by two examples.
