A Novel Method of Dynamic Balance Weighting for Single-Disk Rotor System
Authors: , ,
Abstract: Reasons for rotating mechanical vibration are varied, while the situations on site show that the rotor mass imbalance is the main reason. A novel method of dynamic balance weighting for single-disk rotor system based on equivalent phase difference mapping is proposed. Firstly, the influence coefficient method and its characteristics are analyzed. Secondly, principle on how to measure phase by key pulse method and definition of phase are introduced, and physical meaning of phase by Discrete Fourier Transform (DFT) based on vibration signal triggered by key phase signal is analyzed in detail. Thirdly, the equivalent phase difference mapping relationship between incentive and vibration response for single-disk rotor system is proved by differential equations and Laplace transform theory. Finally, a specific application instance and procedure based on the proposed method are showed. The new proposed method is simple and easy to peel the phase coupling relationship between incentive and response, which can be used to guide dynamic balance weighting for single-disk rotor system on site.
