Numerical investigation of the effects of flowchannel on a performance in a magnetic fluiddamper

Keywords: Magneto-rheological damper, MR damper, Computational Fluid Dynamics, Finite Element Method , Finite Difference Method , Three-Way Coupling Simulation of fluid In this study, considering the working conditions of semi-active magneto-rheological liquid dampers, the magnetic field distribution in the coil and the core region, magneto-rheological fluid region effected by this magnetic distribution and the stress distribution in both the damper wall and the piston region have been investigated. In addition, during the study, temperature changes that result from both solid-liquid and solid-solid friction as well as magnetic field distribution have been established. Thus, the required dynamic range distance and reaction force values were determined according to the damper area to be used. Damper draft design has been established according to these inputs and literature studies. First, different physics environments were simulated and solved separately, the changes in the parameters examined according to different boundary conditions and geometric dimensions have been determined. Then, these two different physics models were studied simultaneously (coupled) and the parameters were with each other and the dynamic effects in the system were investigated. MR damper designs have been examined numerically; The reaction forces of the sinusoidal channel damper according to different wavelengths and amplitudes were analyzed.
