Machine tool information acquisition and separation method based on thermal state characteristic mechanism analysis

The invention discloses a machine tool information collection and separation method based on thermal state characteristic mechanism analysis, and relates to the technical field of machine tools, a large number of sensors are installed in a machine tool, and the installed sensors are heat detection sensors and are mainly used for detecting friction heat of a bearing and heating of a motor. According to the method, the extracted data can be effectively combined by setting the geometric model, the formed information is clearer, the thermal state characteristic information can be more comprehensively collected by calculating the convective heat transfer coefficient, the thermal state characteristic information can be comprehensively collected, data analysis can be combined, and the effect of quantitatively evaluating the performance of the main shaft is achieved; a large number of sensors are arranged and attached to the bearing and the motor, accurate information of the main shaft is calculated by combining temp
