Abstract

PURPOSE:To precisely detect unbalance distribution, by a method wherein a support condition on a support position and a support rigidity in a support part which turns an elastic rotor is caused to vary, and the elastic rotor is caused to turn under different support conditions. CONSTITUTION:A pair of bearings 2 (bearings which support the opposite ends), which rotatably supports an elastic rotor 1, and a pair of bearings 3, which support at another position, are constituted so that they can individually and freely move vertically. Firstly, the bearings 2 at the opposite ends are raised to support the elastic rotor 1 and the other bearings 3 are lowered to be brought into a nonsupporting state. With this the elastic rotor 1 is caused to turn at a rotation speed to measure and analyze a unbalance weight against a critical speed mode in the elastic rotor 1. Then, the bearings 2 are lowered and the bearings 3 are raised to measure and analyze a unbalance weight against a critical speed mode in the elastic rotor 1. Like this, the elastic rotor is caused to turn under different conditions, and this permits the precise detection of a unbalance distribution.
