| 摘 要： | 根据实验过程中煤（岩）试件在峰值强度所表现出了强红外热信息，提出要考虑试件破裂面间及试件破碎颗粒间的磨擦生热的对试件红外热辐射的影响，就两块体间没动磨擦模型进行了分析，指出磨擦面对两块体分别起到固定热源和运动热源的作用，由于热源形式不同，磨擦面对两块体温度场的影响是不同的，根据热源形式的不同，分别给出了两块体上任一点由于磨擦生热而引起温度变化的解析解。

| Abstract: | During the coal (rock) samples?infrated testing, one can observed that the samples?temperature field is varying. Commonly, causes of this varying are owed to samples?plastic deformation and crack extension. But noticed that many coherent documents had indicated that most samples even has high temperature field after the peak strength. This paper put forward that the influence of friction between the fracture planes on the samples?temperature field could not be ignored. Meanwhile, paper gave a simple friction model of two blocks,. In the model, the friction face played the different roles to the two blocks as locomotor heat source and fixed heat source respectively. Those different heat sources have the different effect on the blocks?temperature field. At the end, analytic solutions of temperature change to any points of two blocks that caused by friction are given. |
