Abstract

Traditional rigid-body mechanisms consist of a number of components to implement their functions. Therefore they face problems such as backlash, wear, increase in part-count, weight, assembly cost and time, regular maintenance. Reducing these problems will help in increasing mechanism performance and cost reduction. Recently, there are several examples of compliant mechanisms that have been designed and widely used in various fields such as for adaptive structures, biomedical, hand-held tools, components in transportations, MEMS and robotics. However, the largest challenge was relative difficulty in analyzing and designing compliant mechanisms. Two approaches known in the literature for the systematic synthesis of compliant mechanisms are the kinematics-based approach and the structural optimisation based approach.

Highlights

  • A compliant mechanism can be defined as singlepiece flexible structure, which uses elastic deformation to achieve force and motion transmission[1,2]

  • Adaptive structures: Compliant cable technology was developed by National Aeronautics and Space Administration (NASA) Goddard Space Flight Center

  • Compliant mechanisms have made an enormous contribution in the design process of various fields such as for adaptive structures, components in transportations, hand-held tools, electronics, medical, etc

Summary

INTRODUCTION

A compliant mechanism can be defined as singlepiece flexible structure, which uses elastic deformation to achieve force and motion transmission[1,2] It gains some or all of its motion from the relativeflexibility of its members rather than from rigid body joints alone[3]. The SLP starts with trial design and replaces the Highlights in applications: New competitive products objective function and constraints by linear must meet the growing demands of the market They approximations obtained from a Taylor series must be light-weighted, resource efficient, durable, expansion about this initial design. Adaptive structures: Compliant cable technology was developed by National Aeronautics and Space Administration (NASA) Goddard Space Flight Center In structural connections, these mechanisms provide compliance and dampening. This design eases the sterilization over current MIS tool (c) designs

Compliant mechanisms must tolerate between flexibility and stiffness
