Magnetorheological (MR) dampers have attracted interest from suspension designers and researchers because of their variable damping feature, mechanical simplicity, robustness, low power consumption and fast response. Therefore, optimisation of such devices is of particular interest to achieve optimal vibration control. This study deals with the geometrical optimisation of an MR shock damper using Taguchi experimental design approach. The optimal solutions of the MR damper were evaluated using analytical equations, which give the dynamic range of the damper under consideration. Optimal geometrical values obtained provided most performance in consideration of other nine alternatives of Taguchi experimental design specified for the study.

The nonlinear behavior of semi-active magneto-rheological (MR) absorbers should be described for improving control algorithms. Also, overheating in the working conditions of the MR absorber due to current excitation and high damping velocity seriously changes the characteristic of the MR fluid and causes problems for controllability. The relationship between damping performance and temperature must be defined in the control algorithms that control the absorber when used in a system such as structure, vehicle, and medical haptic. In this work, a new methodology has been presented to describe dynamic behaviours of MR absorber depending on temperature based on the Bouc-Wen model. Seven parameters in the Bouc-Wen model have been evaluated depending on temperature. Thus, damper force has been defined depending on temperature with a single equation that significantly simplifies the control process. When the experimental and the model results have been compared, it was shown that the error rates varied between %0.89 and %8.4. The average errors of the displacement, time and velocity have been 1.75%, 6.6%, and 4.4%, respectively.

Manyeto-Reolojik (MR) sıvı uygun bir manyetik alan ile uyarıldığında, görünür viskozitelerinde çok hızlı ve tersinebilen değişimler elde edilen, akıllı malzemelerin bir türüdür. Manyetik alanın kontrolünün kolay olması, bu sıvıları özellikle sönümleyici olarak kullanılabilmelerine olanak sağlamaktadır. Günümüzde doğrusal çalışan damper (sönümleyici, amortisör) ile, dönel olarak çalışan damper (kavrama, fren gibi) tasarımları mevcuttur. Kısıtlı Açılı Dönel MR (KAD-MR) damper ise, açısal olarak sınırlandırılmış dönme hareketiyle MR sıvıyı bir bölmeden diğer bölmeye aktarırken, belirlenen akış bölgesinde MR sıvının manyetik alana maruz bırakıldığı cihazdır. Bu çalışmada yeni bir KAD-MR Damperin kavramsal tasarımı yapılmış ve tork performansını etkileyen tasarım parametrelerinin, hesaplamalı akışkanlar dinamiği (HAD) yardımıyla, belirlenen hedef değerler için en uygun tasarım parametreleri belirlenmiştir.
