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...

The development of control systems for a two degreeof-freedom vibration suppression system using a magnetorheological (MR) fluid damper is the subject of this paper. It is assumed that system encounters impulsive disturbance forces. The objective is to use the (MR) fluid damper for the position control and vibration suppression of the payload. The control force is generated by regulating the el...

This paper presents the design of second-order sliding mode controllers for semi-active control using magneto-rheological (MR) dampers. The approach can be useful in applications involving shock absorbers but here our main concern is the suppression of building vibrations induced by dynamic loadings such as earthquakes or strong winds. The MR dampers have been of increasing interest in structur...

The paper presents an application of the Skyhook control of suspension MR dampers in a vehicular vibration control system. Experiments were conducted using an ATV (all-terrain vehicle) traversing a test route. The system elements were analyzed and calibrated paying special attention to the space orientation of sensors and MR dampers. Orientation data and inversed Bingham model, which maps dynam...

Due to their extensive use in various applications, helicopters need be able land a variety of conditions. Typically, helicopter landing gear system with skids or passive wheel-dampers is designed based on only one critical touchdown condition. Thus, this may not perform well different A magnetorheological (MR) dampers would promising candidate solve problem. However, semi-active controller mus...

Magnetorheological (MR) damper performance is evaluated only by single-field analysis in the design process, which can easily lead to larger errors. Based on this, a simulation method of MR considering multiphysics coupling was proposed. According certain automobile shock absorber requirement, an suitable for suspension designed. The mechanical model, electromagnetic field flow and structural s...

Skyhook control, which is now widely applied to vehicle suspension control, requires two sensors to measure sprung mass acceleration and relative displacement, respectively. In the practical implementation, these two measurement signals are converted into corresponding velocities; then per the skyhook control policy the velocities are employed to decide the desired damping level; finally the da...
