Modeling and Dynamics Analysis of LiquidFilled Flexible Spacecraft

  • This paper deals with the modeling problem of a spacecraft consisting of a liquid-filled rigid platform and some flexible appendages. The spacecraft is modeled by using the Kane's equations. Hybrid-coordinate and spring-mass equivalent model for liquid sloshing are adopted in the modeling. With two-class appendages, the multi-body open-chain dynamic model can be applied more universally. Simulation results on a sample of tracking and data relay satellite were given to show the validity of the proposed model.
