Torsional vibration analysis
Torsional vibration analysis is an important diagnostic instrument for identifying irregularities during operation of a machine that can lead to damage to rotating parts.
Torsional vibrations cause stresses that add to stress caused by normal rotational motion.
High values of torsional vibration measurements can therefore have disastrous effects by causing damage to equipment, plant, staff and by generating a negative impact to production.
Torsional vibration analysis can be a valid instrument for studying various problems that affect machines:
- High gear noise
- Faster gears wearing and tearing
- Accelerated gear wear
- Gear tooth failure
- Slippage of coupling hubs
- Transmission coupling damage
- Deformation of keys
- Coupling hub creep
- Accelerated wear of electric motor windings
- 45° shaft fatigue failure
- Power fluctuations
SINT can measure the torsional vibrations with strain gauge method (with telemetry system) or with zebra-tape and optical probe.
Telemetry Data transmission
Torque and torsional vibration are measured with the aid of telemetry data transmission systems.
SINT Technology has various telemetry systems and processing software (Field M&D) capable of performing torsional analyses on a wide range of machinery.
- Battery systems
- Inductive systems for long term monitoring
The data transmission and acquisition systems have the following characteristics:
- Easy and quick to install
- Can be fitted on any diameter of shaft
- Straightforward to use
- Accurate transmission of very low level signals (from strain gauge bridges)
- High noise immunity and disturbance immunity.
