端面滑动摩擦副接触界面波段发射率研究
Research on Wideband Emissivity of End-face Sliding Friction Pair Interfaces
摘要
Abstract
In order to investigate the wideband emissivity changing rules of the sliding contact in-terfaces during the friction,a set of experiments were conducted.Taking the end-face sliding interface as the study object,its wideband emissivity after different friction times was measured using thermal imager and self-made device under constant load,constant velocity and molybdenum disulfide grease lubrication.The change regulation of the emissivity was used to correct the brightness temperature obtained by infrared thermometer.The measurement results of the wideband emissivity show a com-paratively accurate ones of the self-made devices.The emissivity of the friction contact interface(with lubricating grease and abrasive dust)fluctuates within a certain range in general,and decreases firstly and then increases during the friction processes.The correction of the brightness temperature shows a high precision in the stable friction stage.关键词
