摘　　要：建立了转子-轴承-密封动力学模型,通过数值积分模拟方法,研究了轴系对中偏心、轴承支承润滑特性、密封力等动态因素对系统振动的影响,其运动行为和各因素对系统运动稳定性的影响,得出了各种因素与系统运动行为之间的相互关系.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.
