| 摘 要： | 针对各种复杂、极端热环境下的表面热流密度测量难题，提出了一种基于红外热成像技术的表面热流密度分布测量方法。热流测量借助贴敷在被测物体表面的特制信标，从红外热图中计算获得各项测量参数。其结合了接触式测量与非接触式测量的优点，区别于传统单点测量可以一次性完成二维覆盖测量，保证测量精度的同时适用于更广泛的工程环境，具有很大的工程及生产实践意义。研究中先后从系统构建、原理分析及数值仿真的角度入手，得到测量的理论误差小于2%，证明了基于红外热图技术的热流密度分布测量方法的可行性与正确性。

| Abstract: | Focusing on the problem of heat-flux measuring in complex and extreme circumstances, a new measuring method based on infrared thermography was proposed. Be superior to traditional radiation heat flow meter which can only measure heat flow at one point, the thermal distribution and heat flow distribution could be gotten easily and accurately in one time with help of a made-to-measure beacon, combined the advantages of contact and non-contact measurement. This study was divided by three parts, theoretical analysis, system construction and numerical simulation. Less than 2% theoretical error was obtained which verifies the accuracy and feasibility of heat-flux measurement technology based on infrared thermography. |
