Abstract

PURPOSE:To minimize the vibration of multispan rotors by obtaining the unbalance amount exising in each single rotor before combination and combining after the optimum phase angles among single rotors to each other are obtained on the basis of the said amount. CONSTITUTION:A memory storage 1 to obtain and memorize the residual unbalance vibration of every single rotor after the balance of the single rotor and another memory storage 2 to memorize the influence number of each single rotor and the influence number after the combination of rotors, are connected to an arithmetic unit 3, which obtaines the equivalent residual unbalance amount on the basis of the influence number method. Then, a combined influence number by an arithmetic unit 4, a mutual combination angle among rotors by an arithmetic unit 5, vibration after the combination of rotors by an arithmetic unit 6, comparison between estimated and allowable vibrations by a decision unit 7, and residual vibration after the addition of balance weight by an arithmetic unit 9, are respectively calculated for obtaining the optimum phase angle.
