As regards a balancing method for a flexible rotor, a modal-least squares balancing method is derived, which has both features of the modal balancing and least squares balancing methods. The effect of each correction mass, which is obtained by the above method, on the vibration is physically clarified. Even if the influence coefficients contain errors initially, they are easily corrected by applying the above method, and a good balancing result is then obtained. It is described by some numerical simulations how the above method is effective for the balancing of the flexible rotor.
