Overview

Analytical model predicts vibration response in hub motor drive systems, highlighting bearing stiffness impact.

Key Points

  • This research aims to explore how bearing stiffness affects the vibration characteristics of hub motor drive systems.
  • Developed an analytical model for bearing contact stiffness under actual operating conditions.
  • Incorporated the stiffness model into the vibration model of the hub motor drive system.
  • Analyzed vibration responses under combined excitations from road conditions and unbalanced magnetic pull.
  • Found that hub bearing stiffness significantly influences the dynamic tire load.
  • Observed variations in wheel acceleration linked to changes in bearing stiffness during different operating conditions.
