We present an extensible-link kinematic model for characterizing the motion trajectory of an arbitrary planar compliant mechanism. This is accomplished by creating an analogous kinematic model consisting of links that change length over the course of actuation to represent elastic deformation of the compliant mechanism. Within the model, the motion trajectory is represented as an analytical fun...

This paper focuses on the complex design process of planar compliant mechanisms with flexure hinges. In the following a systematic methodology of the transition from lever mechanisms generated intuitively by the developer or non-intuitively by topology optimization to applicable compliant mechanism is presented. An extended pseudo-rigid-body model (PRBM) is used for the analysis and the modific...

A systematic method for dynamic analysis of compliant mechanisms is presented including basic formulations for natural frequencies, modes, dynamic response, and frequency characteristics. Methods for design sensitivity analysis are developed to investigate the effect of various design parameters on the dynamic performance of compliant mechanisms. A micro compliant stroke amplifier mechanism, fo...

The design of the canopy utilizes conventional rigid body mechanisms which is vulnerable to presence backlash, friction joints or wearing mechanical parts lead short product life. Compliant are employed reduce these problems, owing their zero-joint and monolithic structure. A reference for was chosen modified through reviewing different patent designs. Six configurations pseudo-rigid-body model...

This article presents the structure and theoretical foundations of the Learning Object Review Instrument (LORI), an evaluation aid available through the E-Learning Research and Assessment Network at http://www.elera.net. A primary goal of LORI is to balance assessment validity with efficiency of the evaluation process. The instrument enables learning object users to create reviews consisting of...

The present study examined the perception of smallholder pineapple farmers on Global GAP standard compliance, assessed compliant farmers’ rate of adherence to standard requirements, and compared the average farm profit of Global GAP compliant and non-compliant pineapple farmers in Akuapem South Municipal Area of Ghana. The study used mainly farm level data solicited from 150 randomly selected p...

A procedure to obtain a topology of an optimal structure considering flexibility is presented. The methodology is based on a mutual energy concept for formulation of flexibility and the homogenization method. A multi-objective optimization problem is formulated as an application of compliant mechanism design. Some examples of the design of compliant mechanisms for plane structures are presented...
