Effects of motorbike front suspension component operation on torsional vibration frequencies

Abstract

Riding a motorbike requires much more experience than other types of vehicles. However, not only insufficient skills may contribute to dangerous driving situations, but also vibrations generated in the steering system of a motorbike. This paper presents a method of vibration analysis on the example of a motorbike steering system using a transmittance model and shows how to extract the relevant frequencies for analysis. The effects of selected stiffness and damping parameters are analysed and an assessment is made of how the frequencies for wobble vibration will change over the life of the steering components. The results were presented using Bode diagrams.
