摘要/Abstract

摘要： 压液式在线自动平衡系统作为一种新型的液体式自动平衡系统，具有结构简单、旋转部分无可动部件、动作环境封闭、平衡过程可逆且可停机保持等优点。相较于已有其他在线自动平衡系统，更适用于大型旋转设备领域。介绍该在线自动平衡系统的组成及工作原理，基于某最大直径达500 mm的转子实际结构，通过有限元仿真对转子-轴承-单/双平衡执行器系统的动力学特性进行定量分析，据此设计的平衡执行器对原转子系统的动力学特性影响在2%以内；分别进行单/双平衡执行器的抑振效果模拟仿真，振幅降低70%以上。最终在模拟试验台上，通过单面自动平衡试验将转子振幅从18.6 μm降至10.6 μm，验证该平衡系统的可行性和有效性；通过双面动平衡将转子振幅从17.8 μm降低至4.6 μm，为后续双面自动平衡研究奠定技术基础。

Abstract: As a new type of liquid automatic balancing system, the pneumatic-liquid online automatic balancing system has the advantages of simple structure, no moving parts in the rotating part, closed action environment, reversible balancing process and can be held after stopping, etc. Compared with other forms of online automatic balancing systems, it is more suitable for large-scale rotating equipment. The composition and working principle of the online automatic balancing system are introduced, based on the actual structure of a rotor with a maximum diameter of 500 mm, the finite element model has been established. The dynamics of the rotor-bearing-single/double balancing actuator system has been quantified, according to which the balancing actuator was designed to change the dynamics of the rotor system by less than 2%. The vibration suppression effect of single/double actuators has been simulated, and the amplitude of the rotor has dropped by more than 70%. The experiment illustrates that the single-sided automatic balancing experiment achieves the reduction of rotor amplitude from 18.6 μm to 10.6 μm, which verifies the feasibility and effectiveness of the balancing system; the reduction of rotor amplitude from 17.8 μm to 4.6 μm by double-sided dynamic balancing which lays the technical foundation for the subsequent double-sided automatic balancing research.

Key words: large-scale rotating equipment, automatic balance, pneumatic-liquid type, dynamic characteristics simulation, structural optimization design
