| 摘 要： | 为了克服在传统的推力轴承油膜温度监控方法中存在的瓦面温度滞后于油膜温度，以及最高油膜温度不易确定等缺点，提出了基于导热反问题分析和插值算法的油膜瞬态温度场重构方法。通过重构的温度场，不但可以解决由瓦体热容导致的测温滞后问题，而且还可以准确确定最高油膜温度值及其出现的位置，数值验证表明，琪于导热反问题分析的推力轴承瞬态油膜温度重构方法可用于油膜温度的在线监控。 |

| Abstract: | In order to solve the problems that pad temperature lags behind oil film temperature and the highest temperature of oil film is difficult to determine in the traditional methods for monitoring oil film temperature, a new monitoring method was proposed. This method is based on the analysis of inverse heat conduction problems, and can inversely deduces oil film temperature from the measurement of thermal resistances embedded under pad surfaces. Numerical tests demonstrate that the method could inversely derive the oil film temperature from the pad temperatures accurately. |
