  • Process and device for automatic identification of increased resonance response during balancing procedure
    Patent number: 5257541
    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.
