Lightweight parallel manipulator’s interests have been increased due to their benefits over rigid ones. Moreover, at high operational speeds structuralflexibility effects are much more considerable. In this manner, developing a proper model to assess the kinematic and dynamic characteristics of structuralflexible parallel mechanisms with the purpose of developing a productive vibration control is outstanding demand. Accordingly, This paper represents thekinematic and dynamic modeling of the 2-PRRRRP planar parallel manipulator with two flexible links,using the assumed mode method modeling andLagrange equations of the first type approach. Dealing with the complicated nonlinear equations is a major goal. The flexible link is designed and modeled in Abaqus software then the simulations are analyzed in MSC.ADAMS coupling with Matlab/Simulink.Furthermore, the computed torque control method is performed toward establishing a profitable vibration control. The results of simulation for the full circulardesired trajectory indicate the productivity of the approach in modeling the flexibility of the links.
