| Abstract: | The finite element method is used for the system discretization and the coupling dynamic equations of flexible beam are obtained by Lagrange's equations. The second order coupling terms between rigid large overall motion,arc length stretch,lateral flexible deformation kinematics and torsional deformation terms are included in the present exact coupling model to expand the theory of one-order coupling model. The dynamic response of the present model is compared with that of zero-order approximate model and o... |
