With regard to the inadequacy and complexity of ANSYS Mechanical APDL and Workbench in the analysis of one-dimensional thermal characteristics of the electric spindle,based on theoretical analysis,establishes the model of ohne-dimensional thermal characteristics for electric spindle.The related programming is completed in MATLAB based on finite difference method,and the temperature distribution of the one-dimensional spindle can be quickly attained with the relevant parameters of the spindle given.The proposed model greatly simplifies the original procedure without the need to adopt ANSYS or other software for analysis purpose.Compared with the result from Workbench analysis,it is found that the two analysis results have high consistency.The achievements of the paper are helpful for finding the"hazard section"of the axial temperature distribution of the spindle and provide reference for the structural design and engineering applications of the electric spindle as well.
