Abstract
To solve the problems of the reconfigurable spacecraft structural dynamic characteristics rapid evaluation considering contact and friction in conceptual design, a rapid predicting method is proposed. Based on the features of a typical reconfigurable spacecraft, the method uses the analysis and identification of dynamic characteristics, model equivalence based on virtual material, and estimation of equivalence data to form the processing flow, and realizes the equivalence of refined model. In the simulation verification, the proposed method is used to predict the structural dynamic characteristics of a conceptual design scheme, and under the premise of accuracy, the efficiency of analysis is improved. The results indicate that the proposed method can support the conceptual design and provide foundation for the iteration and optimization design of reconfigurable spacecraft.
