Simulation and Optimization of Flexible Hooke Hinge

Flexible hinge is a typical flexible element in compliant mechanisms. Hooke hinge is a combination of the two revolutions whose axes go through the same point. It allows the two components have relative rotation of two degrees of freedom along the perpendicular axis. The distributed multi-reeds and large-deflection flexible Hooke hinge with the curve reed as the basic unit is analyzed by finite element simulation, and is optimized in multi-objective. The Hooke hinge after optimization lines with the basic rotation characteristics of Hooke hinge. It can provide the larger two-dimensional rotating schedule. It's unilateral rotation angle can be up to 11.9, and the center drift and input coupling of rotation is small. So this flexible Hooke hinge is a new type of large deformation flexible Hooke hinge which has excellent performance.
