Introduction
Machining and measuring operations are invariably accompanied by vibration.
To achieve higher accuracy and productivity vibration in machine tool must be controlled.
For analysis of dynamic behavior of machin ....etc

Shock absorbers and their performance during the earthquake. In addition, they have investigated the world's tall buildings and have studied a satisfactory level of damper performance. And the results show that not only shock absorbers have acceptable seismic behavior against lateral forces such as wind and earthquakes. However, it has reduced the limitations of building multi-storey buildings. A tuned dampener, also known as a harmonic damper, is a device mounted on structures to reduce the amplitude of mechanical vibrations. Its application c ....etc

Abstract:
In this seminar the analysis of soil-structure interaction effects and of multiple support excitation on the seismic response of long-span cable-supported bridges are presented. The purpose of this seminar is to provide a better understanding of the dynamic performance of cable supported bridges under earthquake excitation, considering the spatial variability of the ground motion and the complex phenomena of soil-bridge interaction, so that such effects can be included in the design and rehabilitation process. Amplification of struct ....etc

Abstract:
A modified friction damper is presented to enhance the performance of conventional friction damper and semi-active variable friction damper. An additional plate is provided between the two sliding plates of a conventional friction damper which results in an additional sliding interface with the same normal (clamping) force. Similar modification is also made to semi-active variable friction damper (SAVFD) to enhance its performance. The enhancement in the performance of the benchmark building is studied under across wind loads ....etc

Innovative Designs for Magneto-Rheological Dampers



Introduction
The main purpose of this chapter is to introduce the topic of magneto-rheological
(MR) dampers to the reader. Also presented is an explanation of the mechanism
through which MR fluid works. Lastly, the project objectives and the approach
taken to evaluate different MR damper designs are discussed.

ABSTRACT
This dissertation proposes simple and efficient control algorithms for seismically excited structures using MR dampers and a smart passive system based on MR dampers. Magnetorheological (MR) dampers are one of the most promising control devices for civil engineering applications to earthquake hazard mitigation, because they have many advantages such as small power requirement, reliability, and low price to manufacture. A number of control algorithms have been adopted for semi active systems including the M ....etc
