项目摘要

The present project developed a high-speed infrared thermographic microscope for dynamic visualization of the tribological phenomena. Several experimental investigations of contact problems were carried out through the use of the developed high-speed infrared thermographic microscope. The results obtained are summarized as follows.1. An infrared thermographic microscope system was developed based on the high-speed infrared camera for evaluating temperature and stress distribution of the contact surface and its surrounding area2. A new technique using infrared thermographic microscope combined with infrared-transmitting materials was proposed for the direct measurement of the surface temperature of two contacting solids. This technique was applied to contact stress measurement, through the accurate detection of small cyclic temperature fields induced by the coupled-thermoelastic effect. Contact stress measurements were made for both flat-on-flat and the Hertzian contact. Excellent images of the contact stress distribution were obtained by the infrared thermography based stress analyzing system, indicating that the present technique was applicable to the visualization and quantitative analysis of the contact stresses.3. The high-speed infrared thermographic microscope was employed to characterize the near-surface conditions associated with fretting contact. Both frictional temperature rise due to interfacial slip and the temperature fluctuation due to thermoelasticity can be measured by this system. The experimental results provide insight into not only the magnitude and distribution of near-surface temperatures, but also the nature of the contact stress field and the mechanics of partial slip fretting contacts.
本项目开发了一种高速红外热成像显微镜,用于摩擦学现象的动态可视化。利用研制的高速红外热像显微镜对接触问题进行了实验研究。主要研究结果如下:1.基于高速红外摄像机研制了一套红外热像显微系统,用于测量接触表面及其周围区域的温度和应力分布。提出了一种利用红外热像显微镜结合红外透射材料直接测量两接触固体表面温度的新技术。该技术被应用于接触应力测量,通过精确检测的耦合热弹性效应引起的小循环温度场。接触应力的测量进行了平对平和赫兹接触。基于红外热成像的应力分析系统获得了良好的接触应力分布图像,表明该技术适用于接触应力的可视化和定量分析.采用高速红外热像显微镜对微动接触的近表面状态进行了表征。该系统既可以测量由于界面滑移引起的摩擦温升,也可以测量由于热弹性引起的温度波动。实验结果不仅提供了深入了解近表面温度的大小和分布,但也接触应力场的性质和部分滑移微动接触的力学。
