Abstract:
Analysis methodology and design theory of magnetorheological fluid (MR fluid) shock absorber based on of Poiseuille flow mode have been parented using Newton fluid model nonlinear Bingham plastic model. In the light of the technician requirements for Changan mini-automobile, a MR fluid shock absorber has been designed and fabricated using commercial MR fluid. We have validated experimentally the nonlinear MR fluid shock absorber model. The experimental results reveal that the analysis methodology and design theory is reasonable and the MR fluid shock absorber for a specific application can be designed according to the design methodology developed.
