摘　　要：为研究可倾瓦轴承参数及工作参数对转子系统振动特性的影响,提出了一种可倾瓦轴承-转子系统轴心轨迹理论计算方法,在不同基础静载荷、间隙比及润滑油黏度下对转子轴颈处轴心轨迹进行分析。结果表明:提高可倾瓦轴承的基础静载荷,减小轴承间隙比,降低润滑油黏度可以减小转子轴颈振幅,提高转子系统的稳定性。In order to study the influence of tilting pad bearing parameters and working parameters on vibration performance of rotor system,a theoretical calculation method is proposed for axis orbits of tilting pad bearing-rotor system.The axis orbits at journal of rotor are analyzed under different basic static loads,clearance ratios and oil viscosities.The results show that the rotor journal axis orbit amplitude is decreased and the stability of rotor system is improved by increasing basic static load of tilting pad bearings,reducing clearance ratio of the bearings and decreasing oil viscosity.
