Introduction – What It’s About
Vibration Measurement & Analysis for Test Benches and Rotating Machinery
Unwanted vibrations in rotating test benches and drive trains can lead to quality issues, increased wear, and costly production downtime. We provide a holistic solution: from precise root cause identification and advanced analysis to tailored corrective actions – all from a single source.
Why Vibration Analysis Matters
- Condition Monitoring & Predictive Maintenance
Modern systems continuously record vibration data such as amplitude, frequency, and acceleration. Deviations can be detected long before failures occur – often 12 to 18 months in advance. - Typical Sources of Vibration
Unbalance, resonance at critical speeds, self-excited oscillations, chatter marks, or reduced tool life are common causes of disturbances. - Measurement Methods & Analysis Techniques
Using displacement, velocity, acceleration, and reference sensors, we perform detailed diagnostics in both the time and frequency domain (FFT, waterfall diagrams, orbits, Bode plots, etc.).

e) Consulting, Calculation & Documentation
We support you with engineering studies, simulation, acceptance testing, and the complete vibration-related documentation process.
Technical Background & Measurement Methods
- Compliance with International Standards
Measurements are performed according to ISO standards (e.g. ISO 10816 for vibration severity evaluation). - Instrumentation & Sensors
- Accelerometers (piezoelectric), displacement probes, velocity sensors
- Typical parameters: frequency, amplitude, acceleration, velocity, displacement
- Portable vibration analyzers for on-site diagnostics and ISO-conform evaluation
- Advanced Methods

- Laser Doppler Vibrometry: non-contact, high-precision measurement – ideal for sensitive applications
Implementation on Request – Everything from a Single Source
Analysis and recommendations are just the first step. If desired, we also take care of the implementation:
- Design modifications, calculations, and component selection
- Procurement and manufacturing of machine parts and standard components
- Test bench modifications and extended commissioning
- Updating and extension of machine documentation
This way you benefit from a seamless process – from diagnosis to practical realization.
