Abstract In this study, a combined simulation and experimental method is suggested to determine the heat flow rate produced by detonation products with a planar thermocouple battery placed inside the test medium. A series of experiments was conducted to measure the temperature of products produced by the detonation of ammonite mixed with quartz sand, sodium bicarbonate, and talc over a detonation velocity range of 2–2.8 km/s. By solving the inverse heat conduction problem, we can obtain a time dependent relation for heat transfer from the detonation products to the flyer plate. It is shown that the temperature of the detonation products in the mixtures and the maximum heat flow to the flyer plate rise with an increase in the detonation rate. A quantitative evaluation of heat transfer to the flyer plate by the explosive detonation products is conducted. It is demonstrated that when thin plates (foils) are used as flyer plates, a preheating of the contact area of the colliding components occurs.

金属爆炸焊接中爆炸物对飞板的热效应

摘要 在这项研究中，提出了一种模拟和实验相结合的方法，以确定在测试介质内放置平面热电偶电池时由爆轰产物产生的热流率。进行了一系列实验，以测量与石英砂、碳酸氢钠和滑石混合的菊石在 2-2.8 公里/秒的爆速范围内爆轰产生的产品的温度。通过求解逆热传导问题，我们可以获得从爆轰产物到飞板的热传递的时间依赖关系。结果表明，随着爆速的增加，混合物中爆轰产物的温度和流向飞板的最大热流均升高。对炸药爆炸产物传热到飞板进行了定量评估。证明当薄板（箔）用作飞板时，发生碰撞部件的接触区域的预热。
