The Study of Elastic Dynamic of the Deployment Mechanism in Large Deployable Reflector

Abstract:

The study regards the ETS-VIII satellite antenna unit deployment mechanism as object, uses multi-body dynamics theory as basement to build the rigid body dynamics model of the unit bodies, adopts the finite element method analysis of bending of elastic deformation of the linkage, to establish a unit elasticity of dynamics model and to research the components of flexible dynamic properties of the cell bodies of satellite antenna development. The result of the research shows that the flexibility of the component will lead to the elastic deformation of the cell bodies, in which beats significantly in the location of the maximum abduction, takes place in the deployment process. The research lies the foundation for the dynamic optimization of design of development structure.
