摘　　要：本文研究了在不同的时间、载荷及速度条件下,GCr15钢摩磨擦损表面层的温度场变化规律,并建立了温度场的数学模型如下:采用该模型在计算机上对红外热象仪测温结果进行了计算机模拟,测量结果与模拟合结果符合良好。In this paper, the rules of changes in temperature field of surface layers of steel G Crl5 under unlubricated sliding of different times, speeds, normal loads were studied. A model of temperature field in the surface layer was set up as the following:T (x,τ) = (1-x/L)f1(τ)+ x/Lf2(τ)-K(τ) sin[(π/L)x]And a computer simulation for thermometric data, which were real-time recorded by a thermal video system was carried out by using a mini-computer according to the model. There was a good fit between the measured data and the calculated curve.
