Experimental Evaluation of Modified Groundhook Car Suspension with Fast Magnetorheological Damper

چکیده
The car suspension setting is always a trade-off between comfort and handling. semi-active damper system seems to be an option for reducing the compromise two demands. This paper deals with effect of magnetorheological on car’s performance, especially tire grip, which was directly measured. A unique test rig developed, experimental trolley fast (response time 3 µs) used in paper. controlled by modified Groundhook algorithm. Compared passive regime, experiments showed 30% improvement when using algorithm adequately set. proved trends that were set simulations.

Design and Performance Evaluation of a Rotary Magnetorheological Damper for Unmanned Vehicle Suspension Systems
We designed and validated a rotary magnetorheological (MR) damper with a specified damping torque capacity, an unsaturated magnetic flux density (MFD), and a high magnetic field intensity (MFI) for unmanned vehicle suspension systems. In this study, for the rotary type MR damper to have these satisfactory performances, the roles of the sealing location and the cover case curvature of the MR dam...
متن کاملDesign and Evaluation of a Magnetorheological Damper Based Prosthetic Knee
In this work, a magnetorheological (MR) damper based above-knee prosthesis is design and evaluated based on its performance in swing phase and in stance phase. Initially, a dynamic system model for swing phase of a prosthetic leg incorporating a single-axis knee with ideal MR damper was built. The dynamic properties of the damper are represented with Bingham parametric model. From Bingham model...
متن کاملApplication of a New Modified Parametric Algebraic Model for Magnetorheological Damper in Vehicle Semi-active Suspension System
The purpose of this paper is to present a new modified parametric algebraic model for MR damper in controlling the semi-active suspension system. Except for its accuracy, modified algebraic model is additionally more preferable in terms of its low computational expenses compared to differential modified Bouc-Wen’s model that is extremely computationally demanding. The control part consists of t...
متن کاملSemi-active vibration isolation of a quarter car model under random road excitations using Magnetorheological damper
Semi active control systems are becoming increasingly popular because they offer reliability of passive systems combined with high performance and versatility of active control systems but with low power consumptions. As Magnetorheological (MR) fluids can produce good controllable damping force under application of magnetic field, MR damper can be used as effective element in semiactive vibrati...
متن کاملDynamic Modeling of Magnetorheological Damper Behaviors
Based on theoretical analysis and experiments, this article proposes a new model for a magnetorheological (MR) damper. The proposed model with a smooth and concise form can interpret the bi-viscous and hysteretic behaviors of the MR damper very well. The parameters in the model have definite physical meanings. The bi-viscous and hysteretic behaviors can be characterized by two parameters 0 and ...
