APPROXIMATE EQUATIONS FOR CIRCULAR HINGE STIFFNESSES

Approximate equations for circular hinge stiffnesses

Flexure hinges are widely used for very high precision mechanisms, such as a high precision linear guide, a nano positioning stage, a robot hand and etc., because of no gap and no friction.Regarding circular hinge stiffnesses, Paros and Weisbord derived exact solutions, but they are unwieldly because of the complexity.Simpler equations are preferre
