摘　　要：利用升降法测试16Mn钢疲劳极限,应用红外热像技术检测疲劳试样的表面温度变化,从而拟合得到疲劳极限值,并将这两种试验方法的结果进行比较,确定红外热像技术在16Mn钢疲劳极限测试的可行性。结果表明,利用红外成像技术测得的疲劳极限在工程误差范围内。The fatigue limit of 16Mn steel was tested by lifting and lowering method, the change of surface temperature of fatigue sample was detected by infrared thermal imaging technology, and the fatigue limit value was fitted through it. Then the two methods were compared to analyze the practicability of infrared thermal imaging technology in fatigue limit test of 16Mn steel. The results show that the fatigue limit value tested by infrared thermal imaging technology is in the range of engineenng error.
