Abstract
A finite beam element model of the spindle which is one of key parts of the high-speed winder is presented in this paper. Critical speeds of the spindle based on the finite beam element model are obtained considering the effect of rotatory inertia, gyroscopic moments, and the damping. Harmonic response analysis of the high-speed winder spindle is developed in two conditions including static unbalance and couple unbalance. The dynamic analysis mentioned above is implemented by using the finite element software ANSYS. Calculation results in this paper are helpful for the dynamic balance of the high-speed winder spindle.
