Tracing method for abnormal vibration of rolling mill and related equipment

The invention provides a rolling mill abnormal vibration tracing method and related equipment, and relates to the technical field of sensors and detection, and the method comprises the steps: obtaining an upper working roller vibration signal and a lower working roller vibration signal of a rolling mill, so as to determine an output signal of a roller system; based on the inherent frequency of the roller system in the ideal state, the actual inherent frequency of the roller system is determined; and determining the source of abnormal vibration of the rolling mill based on the output signal and the actual inherent frequency of the roller system. Therefore, the signal vibration source is found out by processing the characteristic frequency of the rolling mill vibration signal, so that technicians can find problems in advance, and technical support and data support are provided for accurate maintenance of equipment. 本发明提供一种轧机异常振动溯源方法及相关设备，涉及传感器及检测技术领域，方法包括：获取轧机的上工作辊振动信号和下工作辊振动信号，以确定辊系的输出信号；基于理想状态下的辊系的固有频率，确定辊系的实
