This paper presents numerical simulations for balancing a rigid rotor. The influence coefficient and least squares balancing methods are compared, under the assumption that the initial vibration values used to calculate correction masses contain errors. The errors in the initial vibration values are : ( 1 ) errors in amplitude, ( 2 ) errors in phase angle, ( 3 ) errors in both amplitude and phase angle. In the three cases, errors are given in initial vibration at one measuring position. A number of numerical simulations are carried out and a comparison is made between correction masses and residual vibration values obtained by the two balancing methods. The results show that the vibration amplitude obtained with the least squares method is smaller than that obtained with the influence coefficient method.
