In order to solve the structural design problem of missile seeker with high temperature and high loads, a multi-scale topology optimization design method was introduced to optimize the missile seeker. A multi-scale parallel topology optimization method for thermo-mechanical coupled continuum structures under steady-state heat source was proposed. With this method, the equivalent thermal load introduced by heat source was coupled to the force load on the macroscopic scale, and the macroscopic configuration distribution consistent with the thermo-mechanical coupled load was obtained. At the micro scale, the clustering method was used to classify microstructures to improve the computational efficiency and solve the problem of scale separation in macro and micro structures. A multi-scale parallel topology optimization model based on solid isotropic material with penalization model was established with the structural flexibility as the objective function and the volume fraction of materials as the constraint. The sensitivity was analyzed and calculated by the direct method under the thermodynamic coupling condition, and the design variables were optimized by the OC criterion method. Hence, the effective macro- and micro-scales parallel topology optimization model was obtained with thermo-mechanical coupled loads. The proposed method was validated by optimizing a cantilever beam structure and the results showed that the designed structure not only had the load-bearing capacity under thermo-mechanical coupling loads, but also had a certain degree of thermal protection ability. At last, the proposed method was applied for performing the integrated design of the missile seeker structure under the force-thermal coupling condition. A good structure of the missile seeker with both load-bearing performance and thermal insulation performance was designed. The two cases demonstrated that the ideal optimized structures were achieved while ensuring 50% mass reduction. Therefore, this has provided a feasible method for structure integrated design under the force-thermal coupling condition, showing that the present method is rational and valuable in engineering application.
