Paper Abstract

Full suspension mountain bicycles exhibit unwanted suspension movement during pedalling. Damper manufacturers frequently adopt what is known as platform damping to overcome this problem. Such dampers resist low frequency pedalling inputs due to the presence of a threshold or 'platform' damping level. However, this platform compromises shock absorption ability over rougher terrain. In this paper, the authors describe a prototype rear shock absorber that utilises magnetorheological (MR) fluids to implement semi-active platform damping. Results from recent field trials will be presented, and the current status of commercialising the system will be discussed.
