Abstract

A method is described for calibrating a balancing machine, in which a rotor (1) to be corrected is rotatably mounted in bearings (2) and a correction run k is performed, wherein at least one measuring sensor (3) determines an initial vibration of the rotor (1) prior to an imbalance correction and transmits this vibration to an evaluation device (4), which stores the measured value as vibration vector {right arrow over (s)}₀. After an imbalance on the rotor (1) is corrected, a residual vibration of the rotor (1) is measured by measuring sensor (3), transmitted to the evaluation unit (4) and stored as vibration vector {right arrow over (s)}₁. The difference δ{right arrow over (s)}={right arrow over (s)}₁−{right arrow over (s)}₀ formed from the measurement data and the corrected imbalance is stored for compensation run k as δ{right arrow over (s)}_k and {right arrow over (u)}_k by the evaluation unit (4). To undertake a calibration of the machine, one can either determine a process calibration matrix K by solving the equation system S=UK^T using the collected measurement data or one can select an already available process calibration matrix using the initial vibration {right arrow over (s)}₀ and/or imbalance vector {right arrow over (u)} and store it as a calibration matrix in the evaluation unit (4) and use it to calculate an unknown imbalance vector of a rotor (1).
