Original Abstract

Semiactive algorithms have great potential in improving car suspension. One of the damper types with adjustable characteristics, which seems to be suitable for semi-active car suspension, is the magnetorheological damper. Such control algorithms require the ability to switch damping characteristics within one stroke. Time response of car MR dampers is in the range of tens of milliseconds. Although the time response is often ignored in semiactive algorithm simulations, it can influence the suspension efficiency in real systems. The influence of MR damper time response on the modified groundhook algorithm was simulated on quarter-car suspension model and verified on an experimental trolley. Results show that ignoring time response of MR damper during design of the semiactive suspension can reduce overall suspension quality of a real system.
