Abstract

Compliant mechanisms are single-piece flexible mechanisms that use elastic deformation to achieve motion. Compliant mechanisms are often used as coupling structures with piezoelectric actuators to provide stroke amplification. The objective of this work is to develop an optimization methodology to design compliant mechanisms with multiple optimally placed multiple actuator elements. A genetic algorithm approach is used to maximize the output displacement when working against an external spring of specified stiffness. Studies are conducted to determine the effect of volume constraints on active and passive material, external stiffness, applied voltage, and density of the ground structure.
