FVA 589 I / 589 II "The Influence of External Vibration Excitations on Rolling Bearings"

 

Analysis of the external vibration-related damage mechanisms in rolling bearings in the low-load operating condition

 

Results

  • Significant influence of external vibrations on the rolling bearing dynamical behavior
  • Perturbation of the lubrication film (mixed friction) as a result of external vibration excitations at certain combinations of parameters from
    • Vibration excitation and corresponding inertia forces
    • Viscosity properties of the lubrication

Motivation

Previous industrial experiences show an increase in failure rate for rolling bearings in vibration-loaded systems. Conventional service life calculations do not take external vibrations into account. Therefore, the applied vibration excitation sources may not be evaluated for their harmful effects by knowing corresponding vibration amplitude and frequencies. A systematic investigation of these harmful effects caused by external vibration sources is therefore necessary to carry out.

 

Research objectives
