| Abstract: | A four degrees of freedom non-linear dynamical model on vertical vibration system of the medium vertical roller mill had been established. Numeric results of vibration equations was figured out by Matlab software. Used the method of Phase graph and Poincare section to discuss phenomenon of quasi-periodic and chaotic vibrations of the vibration system with the electrical excitation frequency changes. |
