Automatic detection of compulsive forces while balancing rotors - by comparing differences of imbalance measurement values at different revolution rates

摘要

A method for automatic detection of compulsive forces in rotors which are being balanced involves determining imbalance measurement values in each balancing plane for different revolution rates. At least two difference values per correction plane are formed from at least three imbalance measurement values per correction plane in an evaluation device. - A compulsive force is detected when both difference values for a higher revolution rate are lower than for a lower revolution rate and the decrease is of quadratic form.
