| 摘 要： | 以转子呈各向异性、支撑刚度非线性时的自动平衡系统为研究对象，提出一种轴心轨迹重构方法来实时测算稳定的基频振动矢量作为最优自动平衡的控制输入，并在自动平衡试验台上进行了试验验证。结果表明，相较于传统单向传感器自动平衡系统，基于轴心轨迹重构的自动平衡控制输入算法的振动幅值降低了7.54 μm，同比下降约5%。

| Abstract: | A method of axis trajectory reconstruction is proposed for the case of an auto-balancing system with rotor anisotropy and non-linear support stiffness. The method can be used to measure the stable fundamental frequency vibration vector in real time as the optimal automatic balance control input, and its efficacy was demonstrated using an auto-balancing test bed. Experiments showed that compared to the traditional automatic balance system with a one-way sensor, the vibration amplitude was reduced by 7.54 μm, corresponding to a decrease of about 5%. |
