Three-Dimensional Identification for Unbalanced Mass of Rotor Systems in Operation
Applied Sciences, 2018 Unbalanced mass identification is important for rotor systems. Current methods normally use sensors, which only detect vibration in two-dimensional (2D) space. Actually, the rotor systems vibrate in three-dimensional directions.
