Balancing of a Flexible Rotor : Selection of adequate correction planes and determination of correction masses by quadratic programming method

抄録

In balancing a flexible rotor effectively, the selection of the correction planes is a very important problem because ill-selection of the correction planes occasionaly results in excess of correction mass which may be impermissible for that rotor. From this viewpoint, the authors proposed in preceding report a theoretical balancing technique by the quadratic programming method in which the sum of the squares of the residual vibrations after balancing is minimized under such conditions that the amount of correction mass applied to each plane does not exceed a certain limit permissible in that plane. The optimum correction masses can be calculated by means of a computer program based on the quadratic programming problem. This paper deals with a method applied to a flexible rotor with overhung masses and its usefulness is verified by some experiments.
