The Key Laboratory of Optoelectronic Technology and Systems Education Ministry of China, Chongqing University, Chongqing 400044, PR China The research on magnetorheological (MR) damping technology is booming in recent years. Especially on application to vehicles, both good ride comfort and steering stability must be taken into account. Accordingly, high scalability of MR dampers and their magnetic design are of significance. In this article, the magnetic design of an MR damper is proposed, and a finite element (FE) analysis on the magnetic saturation is discussed for the utmost improvement of the high force. Through experimental verification, the damper force is effectively scaled by the magnetic design.
Key Words: magnetic design MR dampers magnetic saturation FEM analysis
