In this study, an MR damper optimisation model was proposed. Taguchi experimental design approach was used for the optimisation model. Taguchi method has been shown to present an effective optimisation. The gap, flange thickness, radius of piston core and current excitation factors were determined to achieve candidate geometries. While determining the factors it was needed to consider ease of manufacturing. Three levels are specified for each of the factors. The results of MR damper were obtained analytically. Dynamic range was a key parameter to be evaluated by Taguchi approach, so dynamic range was response value and it was desired to obtain the highest value of the dynamic range. Nine damper geometries were analysed in accordance with Taguchi's L9 array for 4 factors and 3 levels of each of them. As a result of the Signal-Noise analysis and ANOVA, optimal geometry represented that the highest value of the dynamic range was obtained. After Taguchi experimental design analysis, it can be seen that gap is minimum effect on damper performance. One of the most important reasons of the result is that chosen gap levels are close to providing maximum dynamic range. According to CI at 90%, gap and flange thickness factors have lower confidential levels than the value. So, the two factors can be considered insignificant and are raised error term. The factors should be specified based on ease of manufacturing than that prescribed by the optimum condition for the study. In addition, the influences of factors are relative; they can be different from another study according to specified factors.
