Performance of a Suspension Bridge with Active Vibration Dampers

A Semiactive Vibration Control Design for Suspension Systems with Mr Dampers

In an automotive system, the vehicle suspension usually contributes to the vehicle's handling and braking for good active safety and driving pleasure and keeps the vehicle occupants comfortable and reasonably well isolated from road noise, bumps and vibrations. The design of vehicle suspension systems is an active research field in automotive industry (Du and Zhang, 2007; Guglielmino, et al., 2...

Fault detection and fault tolerant control of vehicle semi-active suspension system with magnetorheological dampers

In engineering application the sensor or actuator fault will lead to seriously damage to mechanical systems. The research of sensor or actuator fault diagnosis and fault-tolerant control is very important to improve the safety and reliability of the system. The paper investigates the fault diagnosis and fault-tolerant methods of vehicle suspension system with Magnetorheological (MR) dampers (ac...

Type-1 and Type-2 Fuzzy Logic Control Algorithms for Semi-Active Seismic Vibration Control of the College Urban Bridge Using MR Dampers

In this study, the application of type-1 and type-2 fuzzy inference system (FIS) in semi-active seismic vibration control of the College Bridge using magnetorheological (MR) dampers is investigated. For this purpose, a detailed 3D finite element model of the bridge fitted with MR dampers is created in OpenSees. The command voltage of MR dampers is determined by employing both types of FISs in M...

Performance of Tuned Liquid Dampers with Different Tank Geometries for Vibration Control of Structures

TLD is a tank filled with water and serves as a dynamic vibration absorber for passive control of structures. This paper addresses the comparisons of TLD performances corresponding to different tank geometries including rectangular and conical shapes. Due to the importance of water and tank weight as a load on top of a building, volume is considered to be a constant parameter in this study. Fir...
