Dynamic balancing simulation based on virtual prototyping technology

Rotor unbalance is the main vibration excitation source of rotating machinery accounting for 60~70% of the total machine fault. In this paper, unbalance fault and dynamic balancing are simulated by the virtual prototyping technology based on the unbalance mechanism and balancing theory. The single-face and double-face dynamic balancing are studied. The results validate the correctness and feasibility of the proposed method. The contribution of this paper is to provide one new way to verify balancing method and analyze balancing error without real test.
