Damper performance is important for the vehicle, especially for the military vehicle. The damper will not only improves driver’s comfort and vehicle safety factor, but also enhances the veracity and the mobility in campaign. Therefore, how to analyze the magneto-rheological damper performance and get more accurate results are extremely important. In this article, first of all, sets up the mathematical model by the desired damper, founds the formula about damping force and simulate analysis by Matlab/Simulink. Then set the relevant parameters and boundary conditions, does the computational fluid dynamics (CFD), numerical analysis of fluid dynamic properties by FLUENT. Manufactured this damper after the optimization design and validated by the test on the experimental platform. The results are shown that this damper’s performance is good for satisfying the actual requests.
