planar flexible curved beam mechanism and a design method thereof

The invention relates to the technical field of structural design. The invention particularly discloses a planar flexible curved beam mechanism and a design method thereof. The design method comprisesthe following steps: carrying out fitting design on an integral structure; the positions of the planar flexible curved beam units are arranged; establishing a relationship between the control point coordinates and the static performance indexes by using an isogeometric method; and classifying according to the degree of freedom to obtain a planar compliant curved beam configuration library with static performance, selecting a planar compliant curved beam unit which meets the degree of freedom requirement and has the optimal static performance from the planar compliant curved beam configurationlibrary, and assembling the selected planar compliant curved beam unit into the planar compliant curved beam mechanism. The method solves the problems that in the prior art, the design method of thecompliant curved beam is la
