Experimental investigation into the shimmy motion of the bicycle for improving model-based shimmy estimations

Shimmy, or wobble, denotes the unstable self-excited oscillatory motion of the wheel around the steering axis and can be found in vehicles with castor wheels. For bicycles this oscillatory motion is normally in the range between 5 - 13 Hz. Shimmy could be frightening, dangerous and even fatal if not controlled in time. The introduction of...
