  • A multi-plane and multi-critical transient dynamic balance method was proposed by rising speed response information of flexible rotor.The flexible rotor multi-critical speed balance correction quantity under the optimal algorithm was put forward.The overall balance can be realized by imbalance information of three times rise-critical-speed re-sponse to suppress multi-critical amount of unbalance simultaneously. Numerical simulation with dynamic balance method applies to two-disk rotor model of two-critical unbalance and three-disk rotor model of three-critical unbalance, respectively. The results show that the method could effectively control the amplitude fluc-tuation of whole rotor system while decreasing critical speed amplitude rate up to 60%-80%.
