Originální abstrakt

The paper describes the comparison of traditional passive suspension to the suspension with MR damper controlled by on/off Modified groundhook algorithm. The MR damper used in the experimental trolley together with current controller has exceptionally short time response of force on control signal – up to 1.5 ms. The MR damper was mounted into experimental trolley, which is scaled quarter suspension car model. The experimental trolley was riding on the road simulator over a bump. The suspension quality was evaluated according to the standard deviation of sprung mass acceleration (the lower value means higher comfort) and according to the standard deviation of force (the lower value means better grip). The results show that suspension system controlled by Modified groundhook algorithm outperforms passive system, but the level of improvement is dependent on the setting of current respectively damping in on and off state.
