Parameter optimization of damper-friction isolation systems using concave friction distribution

Design and Evaluation of Hydro-Pneumatic Friction Damper Suspension System

Perceived comfort level and ride stability are the two most important factors in the evaluation of suspension system in a mobile vehicle. It is extremely difficult to simultaneously maintain a high standard of vehicle ride, handling and body control in the vehicle by using conventional passive suspension system. However, the use of active suspensions would result in better comforts than the pas...

The Earthquake Response Analysis of Isolation Structure with Piezoelectric Friction Damper

A new intelligent isolation system combining a piezoelectric damper with laminated rubber bearing is proposed. and used in a practical example in this paper, LQR and GPC chose as the control algorithm according to the damper. The characteristic of these two kinds of algorithm is analyzed and is used in the civil engineering vibration controlling. The results of the analysis show the performance...

Development of a New Semi-active Friction Damper

Modeling and Analysis of Rotating Seal and Friction Damper; Calculation of Damper Stiffness

In this paper modeling of rotating seal and friction damper is explained using NX7.5 and ANSYS130x64 software. Modeling of any component is very important in analysis of the component. Analysis of rotating seal and damper is carried out using ANSYS130x64 to calculate stiffness of friction damper. Various authors explained methods to calculate stiffness of friction damper. In this paper a method...

High Capacity Variable Friction Damper based on Band Brake Technology

Implementation of high performance controllable damping devices can ameliorate cost-effectiveness of structural systems for mitigation of natural hazards. However, the applications of these damping systems are limited due to a lack of 1) mechanical robustness; 2) electrical reliability; and 3) large resisting force capability. To broaden the implementation of modern damping systems, a novel sem...
