Mr damper master thesis

mr damper design

This thesis presents the nonlinear MR brake to a semi active suspension system e. Specifically, designs for MR dampers that were built for a Mercedes ML and for a Ford Expedition are presented along with their respective test results.

These test results are presented and compared with the original equipment hydraulic dampers. This thesis presents the nonlinear MR brake to a semi active suspension system e. Specifically, two different MR damper designs are discussed along with live-fire test results for the first damper. These applications include dampers for automobiles, heavy trucks, bicycles, prosthetic limbs, gun recoil systems, and possibly others. In particular, special attention is paid to comparison with the Bouc-Wen model analysis. This thesis first introduces MR technology through a discussion of MR fluid and then by giving a broad overview of MR devices that are being developed. Semi-active control has recently received considerable attention in some years, because its strong potential to control devices without imposing heavy power demands.

This section includes a discussion of MR damper types, mathematical fundamentals, and an approach to magnetic circuit design. Show full item record Abstract Magnetorheological dampers, or as they are more commonly called, MR dampers, are being developed for a wide variety of applications where controllable damping is desired.

The dynamic response characteristics of the damper are captured in data collection, random input signals were used for angular velocity and current input. After discussing automotive MR dampers, designs for gun recoil applications are presented.

The first part of this project describes the vibration suppression in passive, active and semi active suspension. In conclusion, recommendations are made for materials as well as for seal selection and other design aspects. The last part presents the evaluation of the dynamic simulation modeling results with the full-scale experimental data. The second part of this work is devoted to derivation of the dynamic model equation of the experimental setup. These applications include dampers for automobiles, heavy trucks, bicycles, prosthetic limbs, gun recoil systems, and possibly others. This thesis presents the nonlinear MR brake to a semi active suspension system e. After discussing automotive MR dampers, designs for gun recoil applications are presented. These hybrid dampers, if pursued further, may develop into controllable replacements for large hydraulic dampers such as those installed on large vehicles and field Howitzers. The relationship between the current and damping force in magneto-rheological brake is nonlinear but in the reality it is possible to control the current of MR brake to reduce the vibration of the system as much as possible, because the nonlinearity of the model depends on the current and angular velocity. Subsequently several mathematical models are used to simulate and analyze hysteresis behavior of magneto-rheological brake.

With the necessary background information covered, MR dampers for automotive use are then discussed. After giving the reader an understanding of MR technology and devices, MR damper basics are presented.
