Description
Areas of application
-
Digital Image Correlation (DIC): Testing for the measurement of rotor blade vibrations during operation
-
Validation: Verification and optimization of measurement results of rotating systems
-
Flutter behaviour: Analysis of aeroelastic phenomena on rotor blades
Technical setup and operation
-
Structure: Four units - base, tower, platform, rotor - for flexible adaptation to the ground and requirements
-
Rotor shaft: Hollow shaft with slip ring for signal guidance; continuous condition monitoring with incremental encoders and acceleration sensors
-
Vibration excitation: Pulses at low speeds; piezo patches induce vibrations at higher speeds (voltages up to 1500 V)
-
Drive: Asynchronous motor with bevel gearbox for rotor speeds between 10-500 1/min
-
Rotor mount: Accommodates rotors up to 2.2 m in diameter
Measurement technology
-
