Industrial Internet Campus
Aalto ARotor Lab
The ARotor laboratory is a full scale rotor laboratory with facilities to measure rotors of up to 25,000 kg. In close cooperation with our industrial partners and the National Metrology Institute of Finland VTT/Mikes, the Engineering Design group in Aalto University Department of Mechanical Engineering, it has a history of rotating machinery related research projects from over two decades. During these projects, many measurement based applications and devices have been developed, e.g. geometry measurement devices for large-scale rotors, bearing ring geometry measurement devices, balancing methods, ultrasonic rotor measurement systems for shell thickness, vibration measurement systems, etc.
Beside the measurement applications, machining applications have also been developed, such as 3D grinding methods to compensate measured geometry errors in large flexible rotors such as paper machine rolls. The developed compensation methods include compensation for dynamic geometry error, which can include deformations caused by the rotational forces and elevated temperatures.
