Phase-free static balancing for high-speed overhanging rotors

In this paper static balancing procedures for a machine with an eccentrically arranged overhanging rotor are discussed. The aim is heuristic method of such based on conventional acceleration measurements without any reference phase information. processes, measured vibration signals proportional to the unbalance evaluated aid stationary signal. Furthermore, limitations concerning balance weights and positions have be considered. our case, we six available holes in at specified radius add combination metal studs predefined weights. speed ranges up 10.000 rpm. experimental results proposed compared well-recognized graphical rigid rotors. Special effort was made use already installed monitoring accelerometer process.
