Paper Title:
Numerical Analysis and Simulation of Vibration Characteristics of the Rotation Shaft with Mechanical Seal System
  Abstract

This paper make the rigid support Jeffcott shaft-mechanical seal system as the research object. Firstly, it establishes the equivalent stiffness matrix and damping matrix of the rotation shaft with mechanical seal in the fixed-coordinate system, then derives the motion equation of the shaft with mechanical seal and applies the numerical simulation method to analyze and gain the vibration characteristics of the rotation shaft with mechanical seal system. Numerical simulation results show that: when the rotation shaft works at the speed of the subcritical speed, the trajectory of centre will change with the speed of the shaft. When the shaft works at the speed of the second supercritical speed, the trajectory of centre will be a limit circle. When the shaft works at the speed of the subcritical speed, the vibration response appear 1X, 2X, 3X and so on component of the vibration, and when Ω is 1/2, 1/3 and so on, 2X, 3X and so on component of vibration is biggest; when the shaft works at the speed of the second supercritical speed, 2X and 2X above component of the vibration is very small, even to zero, and then the trajectory of the centre is a limit circle. When hmin is different, amplitude-frequency diagram of the X direction of the rotation shaft is different. When hmin is bigger ,1X, 2X, 3X component of the vibration is bigger.
