| Abstract: | This paper established the mechanics model and the motion differential equation of a new type of textile spindle-low stiffness & small damp tri-flexible journal bearing supporting textile spindle by theory of low stiffness & small damp flexible support of rotor dynamics and theory of rigid body dynamics. Then critical angular velocity formula of the spindle and its estimating formula were obtained from the motion differential eqaution. Finally critical angular velocity of the spindle was calculated practically in different parameters, and effect of parameter varying on critical angular velocity of the spindle was analysed. Some useful conclusions were reached. |
