【Abstract】 The paper has introduced the design project of Spatial Rod-Cable Deployable Structure.The dynamic model of Spatial Rod-Cable Deployable Structure is set up based on the theory of multibody rigid system dynamics, analyze how to construct constraint equations and relevant Jacobi matrices accurately, and use system constraint equation to analysis the moving state of the system. In the end an example of dynamics simulation is present, the result has a wider range of application and a good prospect in deployable structure field. The calculation result shows that the structure plan of modle is feasible.更多还原
