“…The current spectrum shows that the current fluctuates and has the same frequency as the axial vibration. Therefore, the axial vibrations in the FDS are indicated by the motor current [47].…”

“…Aiming at the machine tool load inertia identification algorithm, Li et al [16] proposed a machine tool working modal identification method to predict the dynamic characteristics of the machine tool at different feed speeds, and concluded that with the increase of the feed speed. Zhang et al [17] established the relationship between the stiffness and frequency of the feed system and the acceleration by establishing a variable coefficient dynamic model with acceleration; Zou et al [18] aimed at For the vertical ball screw feed system, a variable coefficient dynamic model was established considering the gravity change of the spindle system, the magnitude and direction of the inertial force and the variable dynamic characteristics of the vertical ball screw feed system under different accelerations were explored; Liu et al [19] studied the corresponding relationship between the current and the vibration of the feed system by identifying the natural frequency of the feed system by using the inertial force sequence generated by the random dry running of the workbench.…”

“…In 2013-2015, scholars [9][10][11] excited the machine tool with the inertial force produced by the random feed movement of worktable and the spindle. In 2016, Liu X et al [12] used this method as a reference to verify the validity of the proposed current-based modal parameter identification method.…”
