Development and Status of Burning Dummy System

Release time: 2015-08-12 10:30

The research on the burning dummy project originated from the 1960s [12]. Three dummy systems are currently operating in North America, four in Western Europe, two in Japan, and several special systems are being developed.
In 1962, the United States Navy and DuPont jointly developed a burning dummy named THERMO-MAN. It used a computer to control the experiment, record the experimental data, statistically analyze the test results, and draw the experimental results and the areas and areas of the human body before and after the burn Illustration. Basically realized the expected function of the burning dummy. In the 1980s, the University of Minnesota also built a dummy for clothing flammability experiments. The dummy is equipped with 44 thermocouple sensors, which measure the temperature to predict the degree of burns and the burned area of the human skin. The ignition method is to ignite the lower edge of the test garment worn on the dummy with a set of gas flames. But this gas flame cannot completely engulf the dummy, so it cannot simulate all kinds of sudden fires.
In the late 1980s, the University of Alberta, Canada also developed a dummy "Pyroman". As shown in Figure 1-1 below, there are 110 heat flow sensors installed on the dummy surface. The dummy and the suddenly burning flame system are similar to the US military's dummy system. After the six burners installed around the dummy were ignited, the diffuse flame produced by the propane gas completely engulfed the dummy. At the same time, a computer-controlled data acquisition system controls experiments, records and stores data from sensors, calculates potential skin damage, that is, the percentage of second- and third-degree burn areas in the total body area, and plots and prints the results.

Switzerland, Japan and other countries have also developed the second-generation "fire dummy" test device. The collected data is closer to the test conditions under actual combat conditions, simulating the special environment of fire fighting operations, and improving the accuracy of the test and experimental results. [14] .
Domestically, the Shanghai Fire Research Institute has tried to produce a similar combustion dummy, but due to the test device oil pan fire is greatly affected by the environment, the heat flux is unstable, the thermal contact area is uncertain, the thermal radiation screen power is insufficient, and data collection Control system software and hardware upgrades and other problems directly lead to shortcomings such as low accuracy of experimental equipment and poor repeatability of results [15,16]. There are not many other research institutions in China engaged in research in this specific field, and they only stay to the extent of theoretical research. There are very few research institutions or organizations that are actually engaged in the combustion dummy test and scientific experiment. The corresponding theoretical and practical data are very small. Less, reflecting that China's research in this field is still weak.
In view of China's current development and research status, the military and civilian demand for high-performance flame-retardant protective clothing has increased, so it is necessary to independently research and develop instrumented combustion dummy.
