| Abstract |
In this paper, we calculate and analyze the effects of the magnetization characteristics of the solenoid valve of the MR damper on the generation of damping force and the vehicle. First, to calculate the damping force of the MR damper, an analytical calculation program based on MATLAB/GUI is combined with a finite element analysis that can consider geometrical shape and magnetization characteristics. Second, the magnetization characteristics of various magnetic material candidates are measured through experiments.
Third, in order to verify the consistency of the damping force characteristics for each speed obtained through analysis, it is compared with the test results measured by the damper test equipment. Finally, the calculated damping force characteristics are combined with the vehicle dynamics model to analyze the vehicle's driving behavior and vibration under various road conditions.
After analyzing vehicle behavior and vibration damping effects depending on the magnetic material, a magnetic material suitable for the MR damper is finally proposed. |
