The dynamic modeling for planar two flexible link manipulators is discussed. A numeric model based on the Hamilton' s principle is obtained, which describes a distributed parameter model and dynamic equations of joint angles, vibration of flexible links and contact force of constrained planar two flexible link manipulators.On the basis of three assumptions, the dynamic model and quasi-static equations are derived, to test the validity of the model, using controller to control the model, through simulation with Matlab software. The research also provides theoretic instructions for developing dynamic control system with flexible manipulators.
