以红外灯作为激励源,对单灯激励所形成的不同距离的温度场分布进行分析,得出规律,再分别对双灯,四灯,六灯所形成的温度场进行探讨,提出了改进热源、改善温度场分布的方法,得到了具有较好的空间均匀性的热激励源。并以该热源激励复合材料蜂窝结构,得到了较好的检测结果。 Using infrared lamp as excitation source, the temperature distributions of different distances formed by single lamp excitation were analyzed and the law was obtained. Then the temperature fields formed by two lamps, four lamps and six lamps were discussed respectively. The improved heat source , To improve the distribution of temperature field, get a better thermal uniformity of the excitation source. The composite material honeycomb structure was stimulated by the heat source to obtain better detection results.
