Dynamic Balancing of Multispeed Multidisk Rotor

This study proposes a method to balance the multidisk rotor systems of aeroengines. A double screening-based correction plane selection method with constraints, such as balancing effect and trim weight, is proposed in this work. The first screening takes the balance effect of the rotor system as the objective function, and the scheme of the correction planes with the better balance effect is selected in the first screening. The second screening aims to screen the trim weight that satisfies the constraints. The scheme of the optimal trim plane is obtained with the balancing effect coefficients of the unit trim weight. The double optimization method is utilized for the multidisk rotor in the simulation and experiment. Results show that the proposed method can suppress the vibration of multidisk rotors working at high speeds.
