Hanger forces optimization of ground test device on deployable structure

Abstract

When using suspension method to simulate the microgravity environment, part of the hanger forces are used to offset the influence of gravitational field on the deployable structure, while the other part produces additional forces that affect the driving forces and precision of the deployable structure. In order to reduce the adverse effect of hanger forces, and avoid the construction of complex finite element theoretical model, an optimization method based on adaptive genetic algorithm with MATLAB and Nastran co-simulation is proposed. Then, the hanger forces are optimized, and the deployable structure deformation has been reduced 49%. It suggests that the adverse effect of hanger forces has been effectively reduced and the proposed optimization method works well.
