| Summary: | 碩士 === 國立彰化師範大學 === 工業教育與技術學系 === 106 === Magnetorheological fluid damper is a device filled with a magnetorheological fluid in a damper. The magnetic field is controlled by an external current (voltage) so that the magnetic force of the piston inside the damper is changed like an electromagnet. The damping force of the damper is controlled by changing the magnetic force of the piston. As the magnetic force of the piston increases, the viscosity of the magnetorheological fluid in the damper also increases.
The main purpose of this study is to maximize the magnetic flux density and identify the influencing factors from the literature: Piston and Outer Tube Materials, Piston Length, Piston Diameter, Cylinder Wall Thickness, Damper Channel Clearance, Gap Channel Length, Current, Magnetorheological fluid. Magnetic circuit analysis was performed using ANSYS Maxwell, and the optimal parameter combination was found based on the Taguchi method. Analysis of variance analyzes the influence of various factors on the quality characteristics.
This research will help to understand the relationship between structure size, material and magnetic flux density, and provide some contribution to future generations of MR fluid damper design analysis.
