Method for the automatic detection and identification of errors in a balancing machine
A method is disclosed for the automatic detection and identification of errors in a balancing machine during operation, in which a rotor provided with an unbalance is rotatably mounted in a vibratory bearing in the balancing machine and is set in rotation by a drive, the rotational frequency of the rotating rotor and the vibrations stimulated by the rotor are measured and measurement signals which comprise the measured values of the rotational frequency and the vibrations are generated and delivered to an evaluation computer.

Method for fault detection and diagnosis of a rotary machine
Modem rotary machine production requires built-in fault detection and diagnoses. The occurrence of faults, e.g. increased friction or loose bonds has to be detected as early as possible. Theses faults generate a nonlinear behavior. Therefore, a method for fault detection and diagnosis of a rotary machine is presented. Based on a rotor system model for the faulty and un-faulty case, subspace-based identification methods are used to compute singular values that are used as features for fault detection. The method is tested on an industrial rotor balancing machine.
The method includes the steps of positioning a workpiece with a centering surface on a centering clamping member of a chuck, pressing a radial contact surface of the workpiece against a clamping surface of the chuck with a first force, centering the workpiece by clamping the centering clamping member against the centering surface, and pressing the radial contact surface of the workpiece against the clamping surface of the chuck with a second force, the second force being greater than the first force.
