摘要

介绍了转子-轴颈轴承系统的动态分析方法，该系统具有较大的动载荷。通过数值计算对控制方程进行求解。将该系统作为刚性转子的运动方程和支承转子的各轴承油膜的雷诺方程的耦合问题进行分析。在此基础上，提出了轴承间存在相对不对准时的分析方法。对一种由三个轴承支撑的刚性转子在旋转压缩机中的应用进行了分析。分析结果显示了转子运动、轴承载荷特性和对中误差的影响。

Dynamic Analysis of a Rotor-Journal Bearing System with Large Dynamic Loads. Influence of Relative Misalignment between the Bearings on the Characteristics of a Rigid Rotor System.

A method for dynamic analysis of a rotor-journal bearing system, in which large dynamic loads act on the rotor, is introduced. The governing equations are solved by numerical calculation. The system is analyzed as a coupled problem regarding the equations of motion for a rigid rotor and the Reynolds equations for the oil film in all the bearings supporting the rotor. Then, an analysis method for when a relative misalignment exists between the bearings is also presented. A rigid rotor supported by three bearings was analyzed for use in rotary compressors. The rotor motion, the bearing load characteristics and the misalignment influence are shown as the results of the analysis.
