Experimental Validation and Adjustment of the Semi-Active Suspension Numerical Model Incorporating a MR Damping


Article Preview

The purpose of this paper is to experimentally validate the performance of a semi-active suspension incorporating a magneto-rheological damper (MR), where the parameters of the numerical models are often poorly adapted to real responses measured experimentally. To ensure a better representation of a real semi-active suspension, we must consider the internal dynamics of the MR damper in its numerical modeling. By adopting models which demonstrate that dynamic, such as the Bingham and Bouc-Wen models, we can approach the measured responses by adjusting their internal parameters. The law control introduction for feedback control of the semi-active suspension incorporating the internal dynamics of the MR damper allows, through the analysis of its robustness and response time, to better assess its performance. To validate the performance of these models, a comparative analysis was made between the experimentally measured responses by the dSPACE system used as an acquisition and control chain and the calculated or predicted responses. A rapprochement between measured responses and those calculated for the same dynamic characteristics of the test bed is possible by adjusting the most influential parameters of Bouc-Wen model.
