Original Abstract

The paper describes the comparison of magnetorheological dampers controlled by semi-active algorithm with different parameters in one suspension system. Response time, dynamic range and damping in activated state are the most important parameters of MR damper. Without any analysis it is extremely difficult to determine the best setting of these parameters. The analysis mentioned in this study compares acceleration transmissibility of system with different damper parameters. This comparison is based on conversion of transfer function into the newly defined single value - transfer coefficient. The more suitable parameters of MR damper, the lower transfer coefficient is exhibited by the suspension system. The analysis also shows that the high-efficient MR damper should have response time as short as possible. Furthermore, it could be inefficient or even counterproductive to achieve the highest dynamic range for each value of damping in activated state. The method of MR damper quality evaluation helps to define the best parameters of MR damper for the specific suspension system where the damper is going to apply.
