Dynamic Modeling of Compliant Mechanisms Based on 2R Pseudo-rigid-body Model

摘要：

　　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.
