The closed-form compliance equations for combined-parabola-shaped flexure hinge based on the unit-load method

A new type of flexure hinge, called combined-parabola-shaped flexure hinge, is presented in this paper. The closed-form compliance equations of the flexure hinge are derived based on the unit-load method. Based on the compliance equations, the numerical simulation is conducted to discuss the performance of the flexure hinge. The results indicate that, the stiffness of the combined-parabola-shaped flexure hinge decreases as s1 increases, increases as t increases. It possesses the ability to change its motion accuracy and its compliance, which means that it can meet variety requirements in engineering applications.
