Comfort, reliability, functionality performance which provide a longer life cycle requires thourogh understanding and analysis of the vibrations, this is a general rule for most of the static and dynamic when studying the functionality performance of any application. Vibrations is an extremely important issue to consider when designing various systems.The hysteresis in the dampers is very impor...

Vibrations is an extremely important issue to consider when designing various systems. It may lead to discomfort and malfunction or in some cases collapse of structures. To compensate for these vibrations different types of damping devices can be applied. The main focus which the following work addresses has been to look at standard methodology which enables determining the hysteresis from defi...

Human gait is characterized by periodic repetitions of two phases: a stance phase in which a foot is in contact with the ground, followed by a swing phase in which the lower limb swings through after toe-off. The functional necessities of above-knee prostheses are to provide knee locking during the stance phase and damping during the swing phase. Most of the conventional above-knee prostheses a...

Application of Magneto-Rheological (MR) dampers in semi-active vibration dynamics control of a multi-cart system is studied. The dynamics and vibration behaviour of a two cart system is investigated mathematically and an experimental test-rig is employed to verify the model, experimentally. The Bouc-Wen model is utilized to represent the mathematical behaviour of MR damper. Different types of s...

This study investigated the self-sensing mechanism in electromagnetic vibration-based energy harvester (EV-EH) prototype specially engineered for a commercial magnetorheological (MR) damper. The objective of work is to demonstrate that EV-EH unit with specific self-powered feature can also be employed as relative velocity sensor system. To do this, action was experimentally studied over assumed...

The rail irregularities and wheel-rail interactions in a train running at high speeds may result large-amplitude vibrations the train’s car body affect passengers by reducing ride comfort. suspension systems have crucial role improving comfort to an acceptable level. In this context, exclusive magneto-rheological (MR) damper with favorable dynamic range was designed fabricated. MR dampers were ...

A hybrid damper concept is presented here using a combination of Magnetorheological (MR) Fluid (MRF) and Shape Memory Alloy (SMA)-based energy dissipation. demonstration performed utilizing the shear operating mode MRF one-way effect SMA. The damping performance different MRF-SMA configurations investigated corresponding consumption evaluated. We demonstrate that operation SMA dampers complemen...

An electro-rheological (ER) fluid showing trembling shear behavior was fabricated with chitosan particles that had benzene, amine and azo-pendent side groups. This modifiedchitosan dispersed suspension showed four regions in a plot of shear stress against shear rate at high electric field. We analyzed this specific behavior with our suggested model. The model was developed with the spring-dampe...
