Balancing state test system based on equipment operation data

Abstract

This invention relates to the field of dynamic balancing testing technology for rotating machinery, and discloses a dynamic balancing state testing system based on equipment operation data, comprising: a synchronous sampling module, a fundamental frequency vector analysis module, and an influence coefficient adaptive calibration module; the synchronous sampling module collects the key phase pulses and original vibration signals of the rotating equipment; the fundamental frequency vector analysis module extracts the instantaneous rotational speed and real-time fundamental frequency vibration vector; the influence coefficient adaptive calibration module stores a weight matrix characterizing the rotor support features, monitors the variance of rotational speed fluctuations, and when the variance exceeds a preset threshold, corrects the weight matrix based on the complex deviation of the vibration vector to calculate the net unbalance vector of the controlled rotating equipment. This invention utilizes the micro-fluctuations in rotational speed during operation as an excitation increment source to construct a sensitivity model reflecting the characteristics of the rotor support, enabling dynamic balancing testing to break free from the limitation of adding physical test weights and meet the online testing requirements under continuous operating conditions.
