柔顺机构是一种新型机构，由于柔性杆经常承受较大的挠度，从而引入几何非线性，其分析非常复杂。一种新的模型(2R PRBM)可以准确地模拟柔性杆的挠度路径和角度。利用2R PRBM建立了一种新的柔顺机构动力学模型。推导了平面柔性机构的动力学方程。以平面柔性平行导引机构为例，对柔性机构的固有频率进行了动力学分析。数值结果表明了该方法在柔顺机构动力学分析中的优越性。
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.
