A Study of Hydraulic Resistance of Viscous Bypass Gap in Magnetorheological Damper
- Brno University of Technology, Technická 2, Brno, Czech Republic
The paper presents hydraulic resistance of viscous bypass hole in magnetorheological damper. The suitable design of bypass hole is essential for efficient function of MR damper in automotive industry. In the paper analytical hydraulic model of bypass gap is compared with experiments. The commonly used hydraulic model of bypass gap does not agree with experiments.
Keywords: Magnetorheological fluid, MR fluid, MR damper, bypass hole, magnetorheological fluid damper
