| Abstract: | Vibration analysis has been made for a hanging roller blast pulverizer which runs over the vibration standard and its motion equation is a nonlinear differential equation. With nonlinear vibration theory and Melnikov method, chaos limit has been analysed and pointed out that hanging rollers are in chaotic state. Based on numerical computation and online test, effective steps have been taken for the pulverize to change the working state, thus vibration and noise are reduced. |
