Abstract
Based on pseudo-rigid-body model (PRBM), a new model is proposed considering the effect of axial deflection of flexural beam in compliant mechanisms. The axial and lateral deflections of flexural beam are modeled using three rigid links joined by one prismatic (P) pair with a linear spring and one revolute (R) pair with a torsion spring, respectively. The flexural beam subjected to an end force load is simulated by the PR PRBM with two degree-of-freedom. The optimal characteristic parameters of the PR PRBM are determined. The advantage of the new model is illustrated compared with the 1R (one revolute pair) and 2R (two revolute pairs) PRBM.
