Compliant slider-crank mechanisms have been studied several times to gain the advantages of compliant mechanisms. The advantages of compliant mechanisms are precision, reducing cost, having no wear, and reducing weight, all gained by manufacturing them as a single piece without backlash. Compliant slider-crank mechanisms also have a critical disadvantage to solve: axis drift and axis rotation of the output segment. Partially compliant slider-cranks are studied several times, and there is only one study on a fully-compliant slider-crank mechanism, but this mechanism has a considerable axis drift which is not desired motion of slider-crank. This study proposes a fully compliant slider-crank mechanism with minimized axis drift and the largest possible stroke. Proposed mechanism is observed kinematically with the help of pseudo-rigid-body model. A force analysis is conducted with virtual work method. Theoretical solution is verified with finite element analysis and measurements of the manufactured prototype of the proposed mechanism.

On the analysis and design of a novel fully compliant slider-crank mechanism
Tanık, Çağıl Merve; Yazıcıoğlu, Yiğit; Department of Mechanical Engineering (2020)
In the literature, authors have made contributions in the area of partially compliant slider-crank mechanisms those possess 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 preciseness is required. In this paper, we proposed an original “fully” compliant slider-crank mechanism design. To the best of our knowledge, this is the first study in the literature on a compliant slider-crank mechanism with...
Carbon encapsulation of elemental nanoparticles
Livan, Pelin; Öztürk, Tayfur; Department of Metallurgical and Materials Engineering (2018)
There is a considerable interest in the encapsulation of nanoparticles into the carbon cages for a variety of purposes e.g. providing stability in detrimental environments, preventing agglomeration, controlling surface modifications and improving in electrical conductivity etc. The current study deals with the encapsulation of elemental particles and is made up of two parts. In the first part, the encapsulation of elemental particles was studied using a spark discharge generator where an elemental rod used ...
on the analysis and design of a new type of partially compliant mechanism
Tanık, Engin; Söylemez, Eres; Department of Mechanical Engineering (2007)
In this study analysis and design procedures of partially compliant mechanisms using two degree of freedom mechanism model are developed. The flexible segments are modeled as revolute joints with torsional springs. While one freedom is controlled by the input to the mechanism, the motion of the parts are governed both by the kinematics and the force balance. The procedure developed for the analysis of such mechanisms is shown on two different mechanisms: a five link mechanism with crank input and slider out...
Effects of Isoflurane, Halothane, and Chloroform on the Interactions and Lateral Organization of Lipids in the Liquid-Ordered Phase
Türkyılmaz, Serhan; Regen, Steven L. (2011-12-06)
The first quantitative insight has been obtained into the effects that volatile anesthetics have on the interactions and lateral organization of lipids in model membranes that mimic "lipid rafts". Specifically, nearest-neighbor recogntion measurements, in combination with Monte Carlo simulations, have been used to investigate the action of isoflurane, halothane, and chloroform on the compactness and lateral organization of cholesterol-rich bilayers of 1,2-dipalmitoylsn-glycero-3-phosphocholine (DPPC) in the...
Effect of curvature on lower extremity residual limb models
Tönük, Ergin (null; 1999-12-01)
Indentor tests are one of the most common ways for in vivo estimation of human residual limb soft tissue bulk elastic and viscoelastic material properties. Due to large strains and displacements encountered during indentation, elementary strength of materials approaches yield crude approximations of the material properties. A common procedure, therefore, is to construct a finite element model of the tissue in the vicinity of the test site. The material properties of soft tissue are identified by matching th...
