Characterising the interaction of individual wheel drives with traction by linear parameter varying model: a method for analysing the role of traction in torsional vibrations in wheel drives and active damping
Abstract A model based approach for characterising the interaction of individual wheel drives with traction is contributed in this article. The primary aim is to investigate the influence of traction on torsional vibration behaviour in the drive train. The essence of this approach lies in reformulating the nonlinear traction behaviour into its differential form, which enables an analytical description of this interaction in its linear parameter varying model equivalence. Analytical statements on the vibration behaviour for different driving scenarios are inferred from this model and validated with measurement samples from a high performance electric road vehicle. Subsequent influences of traction on the performance of active damping of torsional vibrations are derived from this model.
