This study derives the analytical calculation formula for the output compliance of a notched flexure hinge-based bio-inspired joint linkage mechanism in flexible gripping mechanism. Finite element analysis (FEA) was conducted to investigate the compliance characteristics of three distinct notch-type 3-RRR flexible link. The correctness of the analytical solution was validated by comparing it with the finite element solution. Further investigation into the influence of structural parameters on the performance characteristics of 3-RRR flexible link was conducted, establishing correlation curves between geometric parameters and both compliance and stress-strain characteristics. Through comprehensive comparison, the notch configuration demonstrating optimal overall performance in 3-RRR flexible link was identified.
