Description
Areas of application
-
Experimental aeroelastic investigations for the analysis of flutter behavior and vibration characteristics in turbomachinery
-
Blade vibration excitation for measuring and controlling the vibration behavior, e.g. using acoustic excitation or piezo actuators
-
Integration in test rigs and measurement systems, especially in combination with optical methods such as tip timing
-
Application in low-speed axial compressors (NGAV)
Functionality and properties
-
Measurement variables: Frequency, intensity, vibration modes, amplitudes, phase angles, damping rates
- Acoustic stimulation:
- Non-contact blade excitation to avoid external influences
- Variable adjustment of frequency, intensity and vibration modes
- High flexibility thanks to customizable parameters
-
Ideal for optical measuring systems
- Piezo actuators:
- Electrical excitation via slip rings to control the first bending mode
- Precise control of excitation parameters via electrical power supply
- Adjustable intensity and frequency for detailed analysis
