Effect of Variation in Parameters of a Compliant Micro-Gripper Design

At micro-level operations, to make precise microscopic movements, there is need of aalternative mechanism other than conventional mechanism like compliant mechanism. It is rapidly increasing field where a device that uses the compliance of its structure to achieve mechanical tasks such as force and motion transmission.Due to lack of available space, the new mechanisms should be compact without compromise in their accurate & precise performance. Unlike conventional mechanisms, compliant mechanism is monolithic, joint-free & elastic continua.This paper chiefly focuses on the results of variation of parameters within the design of a compliant micro-gripper that uses semi-circular hinge to transmit motion. According to the requirement of an application, the various dimensions of a micro-gripper can be varied. PRBM (Pseudo Rigid Body Model) approach is used to design the micro-gripper. This paper contains analysis work using FEA software (ANSYS). Keywords -Compliant mechanism;PRBM;monolithic;elastic continua.
