【Abstract】 In most balancing procedures currently in use, test weights and runs are required for the calculation of correction masses. A new rotor balancing method without test weights is developed, which uses the balancing objective and optimization considerations of influence coefficient method. By calculating theoretical unbalance responses and measuring original unbalance vibrations, a new type of intelligent optimization technique, genetic algorithm, is applied to the correction mass optimization for minimizing residual vibrations at selected measurement locations and balancing speeds. Experiments show that the residual vibrations can be reduced effectively.更多还原
