摘要：

As a major source of undesired vibration, unbalance is a ubiquitous phenomenon for many types of rotor system. To suppress the unbalance vibration and avoid the complicated and dangerous process of taking trial weights during the balancing process, a model-based balancing method of rotors is proposed in this paper. The rotor model is built to analyse the dynamic characteristics of the unbalance rotor, an unbalance identification method is presented and the optimization objective function of the unbalance vectors is given, then the differential evolution algorithm is employed to acquire the optimization solution. Finally, the accuracy of the rotor model is verified by modal tests, and the performance of the proposed method is evaluated in balancing experiment, results reflect its effectiveness.
