摘要

为揭示转子-轴承系统在不同涡动状态下的产热机理，明确不同涡动状态下的轴颈温度分布特性，提出了一种考虑轴颈同步涡动的转子-轴承系统热效应分析方法。以热效应分析模型为基础，借助C++语言编写用户自定义函数（UDF）引入了温度-黏性模型，采用基于结构化网格的非定常动网格更新方法，实现了同步涡动时轴颈中心的自动迭代。通过算例验证并与Kucinschi实验结果对比，证明了提出的数学模型和求解方法的有效性，探究了轴颈在3种涡动轨迹下，偏心率、同步涡动频率、涡动幅值对轴颈周向温度及压力分布特性的影响。结果表明：当轴颈偏心率固定为0.5、同步涡动频率从50 Hz增大至200 Hz时，直线轨迹下周向温差最大，其与圆轨迹和椭圆轨迹下周向温差的最大相对偏差分别达到了11.51%和14.01%；当轴颈涡动频率固定为159.17 Hz、偏心率从0.1升至0.5时，直线轨迹下的周向温差最大，其与圆轨迹和椭圆轨迹的周向温差的相对偏差均在10%~25%之间；轴颈周向温度分布与油膜黏性剪切力分布具有相位差。研究可为抑制转子热致同步振动失稳提供理论参考。

Abstract

To suppress the heat generation mechanisms in rotor-bearing systems and clarify the temperature distribution characteristics of the journal under different whirl conditions

a method to analyze thermal effect of rotor-bearing system considering synchronous whirling of journal was proposed in this paper. Based on the thermal effect analysis model

a user-defined function was developed in C++ to incorporate the temperature-viscosity model. The unsteady dynamic mesh updating approach based on structured grids was used

enabling automatic iteration of the journal center during synchronous whirling. The effectiveness of the proposed mathematical model and solution method were verified by validation through case studies and comparison with Kucinschi's experimental results. The influence of eccentricity

synchronous whirl frequency

and whirl amplitude on the circumferential temperature and pressure distribution characteristics of the journal was studied under three different whirling orbits. The results show that with a fixed eccentricity of 0.5 and an increase in synchronous whirl frequency from 50 Hz to 200 Hz

the maximum circumferential temperature difference was observed under a straight-line orbit

with the maximum relative deviations from the circular and elliptical orbits reaching 11.51% and 14.01%

respectively and that with a fixed synchronous whirl frequency of 159.17 Hz and an increase in the eccentricity from 0.1 to 0.5

the maximum circumferential temperature difference was again observed under the straight-line orbit

with relative deviations from the circular and elliptical orbits ranging from 10% to 25%. A phase difference was observed between the circumferential temperature distribution and the oil film viscous shear force distribution of the journal. This study can provide a theoretical reference for suppressing rotor thermal-induced synchronous vibration instability.
