对利用可控平衡头实现转子自动平衡的可行性进行了理论分析和试验论证，在导得的自动平衡原理方程的基础上，提出了平衡头的控制策略。研制了新型平衡头和相应的计算机控制系统。试验结果表明该自动平衡系统不需停机即可实现转子在运行期间的自动平衡。这种技术在汽轮发电机组、锅炉引风机等旋转机械上有很大的应用前途。 The feasibility and feasibility of using the controllable balancing head to realize the automatic balancing of the rotor are theoretically analyzed and experimentally demonstrated. Based on the principle equation of the automatic balancing, the control strategy of the balancing head is proposed. Developed a new balance head and the corresponding computer control system. The test results show that the automatic balancing system can automatically balance the rotor during operation without shutting down. This technology has great application prospects in the rotating machinery such as steam turbine generator and boiler induced draft fan.
