A Two-stage Cable Length-driven Layout Optimization Method for Components with Heat Pipe-related Constraints
For the case that the cable length is required to be considered during the spacecraft overall layout design problem,a two-stage heat pipe-constrained component layout optimization method is proposed with the objective of minimizing the cable length.To tackle the coupling layout difficulty caused by many complicated design constraints involved in geometry,system centroid,heat pipe-related dissipation and cable length,a divide-and-conquer strategy is applied to decompose the original problem into two independent optimization subproblems.Then both subproblems are modelled and solved sequentially using mixed integer programming technique,thus efficiently generating optimal layout designs of components on the heat pipes-embedding bearing plate with the compromise of simultaneously shortening multiple cables.A numerical layout example,involving 15 components and 3 wired routes,demonstrates that the proposed method can efficiently and successfully find optimal layout solutions in various optimization scenarios under the two-stage solving framework,which is proven to be feasible and effective.
