The purpose of shock absorbers are to dissipate impact energy, and control tire force variation, the shock absorber has great influence on both ride and handling performance of vehicles, and a great many previous researches have been done on modeling and simulation of the shock absorber. In this paper, a detailed model of shock absorber is established, which contains rebound chamber, compressio...

Semi-active Fuzzy control of quarter car system having three degrees of freedom and assembled with magnetorheological (MR) shock absorber is studied in present paper. First, experimental work was performed on an MR shock absorber under different excitation conditions to obtain force-displacement and force-velocity curves. Then, for the application of experimental data in semi-active quarter car...

The main objective of this article is to present the semi-active vibration control using an electro-rheological fluid embedded sandwich structure for a cantilever beam. ER fluid is a smart material, which cause the suspended particles polarize and connect each other to form chain. The stiffness and damping coefficients of the ER fluid can be changed in 10 micro seconds; therefore, ERF is suitab...

Suspension is the general name of device that connects conductive force between car body and wheels. Among them, operational stability ride comfort are two contradictory requirements in actual driving. In traditional vehicle suspension system, order to maintain vehicle, vibration energy caused by uneven road surface usually dissipated passive shock absorber form heat. If this part can be recove...

In classic passive suspension design, comfort and road handling are conflicting design criteria. An active or semi-active suspension offers the possibility to vary the damper characteristics along with the road profile. Such systems have discrete settings or are limited in bandwidth up to 10Hz. This paper discusses the development of a controller for a passenger car using a recently developed a...

The article presents the amplitude measurement used in the diagnosis of hydraulic fluid leakage from the shock absorbers of passenger cars. Measures used to assess the distribution of the peak using the free vibration method with force extortion. To verify the results of study the FFT were used. In particular illustration of a random vibroacoustic process, acceleration of sprung mass for front ...
