Compliant mechanism is a kind of new type mechanism and its analysis is very complex because flexible links often under large deflections which introduce geometry nonlinearities. A new model (2R PRBM) can simulate accurately both the deflection path and angle of the flexible link. A new dynamic model of compliant mechanism is developed using the 2R PRBM. The dynamic equation of planar compliant mechanism is derived. The dynamic analysis on the natural frequency of compliant mechanism is obtained in the example of a planar compliant parallel-guiding mechanism. The numerical results show the advantage of the proposed method for the dynamic analysis of compliant mechanisms.

This paper presents a comparative kinematic and dynamic analysis of a Delta parallel robot based on numerical simulations of the rigid vs. flexible links robot models. The flexible links numerical models are derived using AutoFlex module of Adams software. Finally, the conclusions regarding the obtained results useful in manipulator constructive design are presented.
