Abstract: | The nonlinear dynamic
problems of three dimensional flexible multibody systems are investigated. The elastic
deformation fields of flexible space beams are decomposed into axial deformation and
bending deformation, and described by each exact vibration modes in the body coordinate
systems. The constrainted nonlinear dynamic equations are derived by using Lagrange
multiplier method. A numerical procedure for solving the resulting differential algebraic
equations is presented based on Newmark direct integration method combined with the
modified Newton-Raphson iterative method. Numerical results verify the effectiveness of
the proposed method. |
