Modelling of torsional vibrations in a motorcycle steering system (Q2067040)

The modeling of torsional vibrations in the steering system of a motorcycle is discussed in this paper. The presented models are used to analyze the vibration sensitivity to changes in motorcycle parameters. The paper presents a method of model synthesis including the determination of nonlinear equations of motion in an extreme ``expanded'' version, then their linearization, Laplace transformation and determination of the transfer functions, frequency analysis based on Bode plots, reduction of the transfer functions and finally calculation of state equations allowing a synthesis of the active damper algorithm. Based on simulation investigations, it is found that the developed damper's regulator works correctly in various traffic conditions. The paper is useful to automobile engineers.
