Recently, a new type of mechanism called compliant mechanism has been developed and applied mainly in the field of micro-mechanics. A compliant mechanism has flexible parts to stabilize the structure, which is contrary to the conventional unstable mechanism. Although a compliant mechanism is usually modeled as a continuum with elastic joints, it is possible to generate the similar mechanism by ...

In this paper we present the synthesis of novel reactionless spatial three-degrees-of-freedom (3-DoF) and 6-DoF mechanisms without any separate counter-rotation, using four-bar linkages. Based on the conditions of dynamic balancing of a single planar four-bar linkage developed elsewhere, the spatial problem is shown to be equivalent to ensuring that the inertia tensor of reactionless four-bar l...

Analysis of the curvature properties of the link lengths of a four-bar mechanism via Mathematical Modeling Techniques using MATLAB Software. The proper identification of the lengths which has been taken analytically using Freudenstein’s equation, which is an experimental work as well as virtual visualization of the work & the model of a 4-bar linkage ,whose modeling has been done through MATLAB...

Four-bar linkage mechanisms are of interest for many specialists in the academia and industry. However, it is one of the mechanisms that is highly nonlinear and exhibits complex behavior. Therefore, it is difficult to model and control their dynamic responses. In this paper, various control schemes are explored and tested on the four-bar mechanism to investigate the dynamical performance under ...

Many mathematical and intuitive methods for constraint analysis of mechanisms have been proposed. In this article we compare three methods. Method one is based on Grüblers equation. Method two uses an intuitive analysis method based on opening kinematic loops and evaluating the constraints at the intersection. Method three uses a flexible multibody modeling approach which facilitates the analys...

The binding affinity of a curvature-sensing protein domain (N-BAR) is measured as a function of applied osmotic stress while the membrane curvature is nearly constant. Varying the osmotic stress allows us to control membrane tension, which provides a probe of the mechanism of binding. We study the N-BAR domain of the Drosophila amphiphysin and monitor its binding on 50 nm-radius vesicles compos...
