“…Kim and Lee [4] recognized the sensor runout with the influence coefficient method without applying additional sensors and equipment and applied the influence coefficient method to the harmonic vibration suppression of the flexible rotor. Kang et al [5] used an automatic balance method based on the influence coefficient method. The influence coefficient balancing equations, with suitable constraints on the level of the residual vibrations and the magnitude of correction weights, were cast in linear matrix inequality (LMI) forms and solved with the numerical algorithms developed in convex optimization theory by Untaroiu et al [6].…”

The unbalanced vibration of the spindle rotor system in high-speed cutting processes not only seriously affects the surface quality of the machined products, but also greatly reduces the service life of the electric spindle. However, since the unbalanced vibration is often distributed on different node positions, the multinode unbalanced vibration greatly exacerbates the difficulty of vibration control. Based on the traditional influence coefficient method for controlling the vibration of a flexible rotor, the optimal influence coefficient control method with weights for multinode unbalanced vibration of flexible electric spindle rotors is proposed. The unbalanced vibration of all nodes on the whole spindle rotor is used as the control objective function to achieve optimal control. The simulation results show that the method has an obvious control effect on multinode unbalanced vibration.

“…The main methods are using electromagnetic bearing or piezoelectric actuator. The acceleration feed-forward method is proposed to reduce the excited response of impact vibration and forced vibration on the rotor [17,18]. In fact, the input-output relationship of control system in electromagnetic bearing cannot be exactly expressed by transfer function, which brings difficulties to design and accuracy control.…”

A novel hybrid bearing with the introduction of piezoelectric controller and tilting pads to control vibration actively is proposed in this paper, and the feasibility of this scheme is verified by theoretical calculation and experimental data. This scheme can control the vibration of bearing actively by using the electromechanical characteristics of piezoelectric ceramic transducer (PZT) components. The static internal character of PZT and static external characteristic of piezoelectric control component are analyzed, and the calculation equations of preload coefficient and driving force of the new bearing are given. The simulation setup of the new bearing is designed and developed. The data representing the relationship of displacement of pad pivot, driving force, voltage, and the simulation stiffness of liquid film are obtained in the test, and the feature parameters of piezoelectric control component are amended to analyze the relationship between preload coefficient of the bearing and driving voltage. The proposed new bearing has the function of controlling preload actively. The theoretical and experimental research results provide essential guidance for the detail design of this new bearing and also provide a new idea for the vibration control of high speed rotor systems.
