Abstract
Abstract A process and device providing automatic identification of increased resonance response during a balancing procedure on permanently calibrated, hard-bearing balancing machines. Unbalance values are determined for each bearing plane of a rotor being balanced for at least three measuring speeds. At least two difference values of speed-related adjacent unbalance values are determined in an evaluation device. Increased resonance response is determined if the difference values between adjacent higher measuring speeds are proportionally greater than those between adjacent lower rotational speeds.

A process for automatic identification of increased resonance response during a balancing procedure on permanently calibrated, hard-bearing balancing machines comprising the steps of determining unbalance values for each bearing plane of a rotor being balanced for at least three measuring speeds, generating at least two difference values of speed-related adjacent unbalance values in an evaluation device, determining an increase in resonance response if the difference values between adjacent higher speeds are proportionately greater than those between adjacent lower speed, and displaying measured values of unbalance when increased resonance response is not found.
