To investigate whether the motorized spindle meets its technical specifications under working conditions, it is critical to analyze the performance of its rotor. Firstly, the three-dimensional model of the motorized spindle rotor is constructed. To study whether the rotor meets the load-bearing performance requirements, the static performance of the rotor is analyzed by ANSYS software to determine the maximum axial displacement of the front end of the motorized spindle rotor under working conditions. While working under the constraints of both axial and radial aerostatic bearings, the modal analysis of the spindle rotor is carried out and its natural frequencies and corresponding modes are obtained. Then, the harmonic response of the spindle rotor is analyzed to verify whether the axial runout requirement can be satisfied under the working conditions of the spindle. Finally, the stiffness test platform of the aerostatic thrust bearing and the modal test platform of the spindle rotor are designed.
