| Abstract: | The principle of virtual work in dynamies of elastic systems is extended to apply on dynamics of flexible manipulators. And the finite element dynamics models including the elasticity and viscous damping at joints are established. The non-linear rigid-body motions and elastic deformation coupling terms are included in the models. Kinematic relations of the coordinate systems on links are reduced to recursive form. The present method is simple in derivation, efficient in calculation, and may be used for analyzing the complete behaviour of robotic manipulators with complex-shape flexible links. |
