  • fatigue analysis (FA)
  • optimized operating and maintenance concepts

Torsional vibration analysis (TVA)

Torsional Vibration Analysis TVA

A torsional vibration analysis permits the loads occurring in a drive line caused from torsional vibration and resonances to be assessed. Alternating torques, power losses, angular accelerations etc. are taken into account and their influence on the lifetime of the drive components is assessed.

A TVA in the project planning phase of a drive system is widely supported on the­oretical data, as practical data is not (yet) available. In some such cases, we there­fore recommend that the calibration is retrospectively calculated by a torsional vibration measurement (TVM). In addition, torsional vibrations analyses are recommended to optimize existing drive systems.

The costs for a TVA are almost always only a fraction of the costs incurred due to torsional vibration damage. A torsional vibration analysis and the associated as­sessment effectively prevent high lifecycle costs (LCC) for your vehicle or plant.

Torsional vibration measurement (TVM)

Torsional Vibration Measurement TVM

Torsional vibration measurement records the loads occurring in a drive system caused by torsional vibration. Knowledge of these loads enables predictions to be made about the lifetime of the drive components. It helps you decide what measures are required to reduce vibrations.

Frequent reasons for performing a TVM:

  1. Prototype test
  2. Causal research in case of loss
  3. Causal research in case of unusual vibrations and increased noise emission
  4. Preventive torsional vibration monitoring

Your benefits

  • Precise knowledge of loads in the drive system
  • Prevention of premature failures of individual drive components or the entire drive system
  • Initiation of selective measures for vibration reduction
  • Validation of the drive design
  • Time and cost saving during troubleshooting

  • Performance of torsional vibration measurements on drive systems with or without Voith coupling
  • TVM methods adapted to the application concerned
  • Preparation of a meaningful TVM report with an analysis of the measurements

Fatigue analysis (FA)

Fatigue Analysis FA

In many sectors, fatigue analyses have become an established part of the de­velopment process. They optimize the lifecycle costs (LCC) and help with the planning of preventive maintenance measures.

The fatigue analysis for your Voith coupling is usually based on data obtained from a torsional vibration measurement during the prototype phase.

We calculate the expected lifetime of wearing and fatigue parts, including elastomers.

Your benefits

  • Optimized preventive maintenance measures
  • High vehicle or plant availability
  • More predictable life cycle costs
  • Optimized return on investment costs
  • Avoidance of changes to the drive design following commissioning

Our services

  • Performance of fatigue analyses for your Voith coupling (other drive components on request)
  • Preparation of a meaningful report
  • Advice on all maintenance issues
