Abstract
Abstract. In the literature, authors have made contributions in the area of partially compliant slider-crank (rocker) mechanisms possessing rigid joints that may cause backlash inherently. On contrary, fully compliant mechanisms offer no backlash which is a valuable property for the cases where high precision is required. In this paper, we proposed a fully compliant slider-crank mechanism that performs large stroke. Kinematic performance of the mechanism is investigated analytically. Dimensions of the mechanism are optimized to obtain maximum translational output, while keeping deflections of flexible hinges equal to each other and as small as possible. A design table displaying stroke, axis drift of the output segment, and critical stresses of compliant segments are presented. As an example, a compliant mechanism is designed by using rigid body replacement technique. Then, via nonlinear finite element analysis technique, analytical results are verified. Finally, a prototype is built to compare output stroke and axis drift with analytical approaches. The results of experiments verified that the theoretical approaches are consistent.
Highlights
Compliant mechanisms are flexible mechanisms that transfer some or all of their motion through deformation of elastic segments. They are divided into two main categories; partially or fully compliant mechanism
Yu et al (2016) proposed a new three degree-of-freedom (DOF) model based on Pseudo-rigid-body model (PRBM) for large deflection beams
There are some fully compliant slider-crank mechanisms available www.mech-sci.net/11/29/2020/. Those are not optimized for large stroke and minimum link rotation
Summary
Compliant mechanisms are flexible mechanisms that transfer some or all of their motion through deformation of elastic segments. Fully compliant mechanisms obtain all their motion from deflection of compliant segments (Howell, 2001). This property is advantageous for the cases where precision is crucial. Tanık et al.: On the analysis and design of a fully compliant large stroke slider-crank (rocker) mechanism ing and twist. In Pardeshi et al.’s (2017) study, monolithic compliant slider-crank mechanism with a rigid slider for motion amplification was proposed. Dao and Huang (2014) proposed an optimal design of a partially compliant slider-crank mechanism with circular cross-section flexure hinges. There are some studies based on compliant linear-motion mechanisms which can not be categorized as slider-crank mechanism: Pavlovicand Pavlovic (2009) introduced compliant parallel-guiding mechanism’s design procedure. We prefer to name the mechanism as slider-crank disregarding the link proportions
