Taking the large typed analytical finite element software ANSYS as a platform,the computer-aided simulative analysis was carried out on the characteristics of static force of a satellite-loaded detector monomer structure under launch condition.The sub-model method used to simulate partial structure has been advanced,thus solved problems in the aspects of modelling,calculation and output of result for complicated structure.The result proved that the proposed method is more effective and accurate than the conventional method.Conclusions with rather higher reference value to structural design have been obtained.A quite successful example is provided for the application of ANSYS in the respect of structural design.
