Dynamic modeling of a flexible beam with large overall motion and nonlinear deformation using the finite element method
对于具有大范围运动和非线性变形的柔性梁的有限元动力学建模

In this paper,the dynamic modeling theory of a flexible beam,which incorporates large overall motion and nonlinear deformation,is investigated. As we knows,in spacecraft and space station,there are a lot of flexible appendices,the dynamic modeling of a flexible beam is essential. Yet existing such models,in our opinion,lack several important coupling terms. This paper supplies these important coupling terms. It is reasonable to use geometrically nonlinear deformation fields to demonstrate and simplify a fle...
