聚能射流侵彻弹坑附近温度分布的测量

MEASUREMENT OF TEMPERATURE DISTRIBUTION AROUND A CAVITY PENETRATED BY SHAPED CHARGE JET

从理论和实验上研究聚能射流侵彻靶板时用薄膜热电偶测量靶内弹坑附近温度的可行性，热偶箔厚30nm。测量结果给出环氧玻璃钢和中碳钢靶板弹坑附近的温度分布，与观察到的实验现象一致。结果不仅证明所用测温方法是有效和可靠的，而且所得结果对研究穿、破甲机理有重要的参考价值。

The feasibility of measuring the instantaneous temperature around a cavity on a metallic or non-metallic target penetrated by shaped charse jet is theoretically and experimentally studied.The thic kness of the foil thermocouple used is 30nm.Results of measurement around a cavity on a target made of epoxy-glass fiber reinforcement composite and on a medium carbon steel target agree with the observed phenomena.It is proved that the method of temperature msasurement is effective and reliabe.Measurement of temperature distribution provides important data of reference in the study of mechanism of penetration.
