| Abstract: | The dynamic systems, such as generator rotors and ship propulsion shafts, include transmis- sion shafts, bearings and seals, which is a typical rotor-bearing-seal dynamic system. When the sys- tem is running, some factors, including shaft mass eccentricity, bearing lubrication properties and seal force, change the system running stability and make it into different movement conditions. The dy- namic equations are given in the paper. With the numerical integral method, the influences of shaft mass eccentricity, bearing lubrication properties and seal force on the dynamic system are investiga- ted. Some relationships between the factors with the system running stability are offered in the paper, which are very significant in theory. |
