ABSTRACT
This chapter presents the optimized design of the parallel bridge displacement amplification mechanism. The first choice is to determine the type of flexible hinge suitable for cell puncture mechanism; parallel bridge displacement amplification mechanism is further proposed to improve the lateral stiffness. The finite element numerical calculation is performed to analyze the static and dynamic characteristics of the designed cell puncture mechanism utilizing rigid-flexible coupling theory. Multi-objective optimization and sixth-order modal analysis are also carried out to verify the correctness of the numerical calculations using Ansys software. Comparative analysis is accomplished showing that the mathematical model of parallel bridge displacement amplification mechanism has high accuracy.
