Detailed explanation of the actual meaning of the combustion dummy

The research of the combustion dummy project was the earliest originating in the 1960s 12. At present, there are 3 kimonies systems in North America are running. There are 4 sets in Western Europe, 2 sets in Japan, and several special systems are being developed.

In 1962, the US Navy United DuPont jointly developed a combustion fake person named thermo-man. It used a computer to control experiments, record experimental data, statistical analysis test results, and draw experiments and fake people before, Burns area and area human body chart. The expected function of the combustion fake person is basically realized. In the 1980s, Minnesota University also built a fake person for clothing combustion experiments. The dummy is equipped with 44 thermocouple sensors, predicting the degree of burns of human skin and burn areas by measuring temperatures. It is ignited to ignite a set of gas flames in the lower edge of test clothing in the dummy. But this gas flame does not completely swallow the dummy, so it cannot simulate a variety of sudden fire.

In China, the Shanghai Fire Science Institute has tried similar combustion fake people, but because the test device oil discharge was significantly affected, the heat flux was unstable, the heat contact area was uncertain, heat radiation Insufficient screen power, data acquisition control system software and hardware upgrade, etc. China's research institutions, engaged in research in this particular area, and only stays to the degree of theoretical research, truly engaged in combustion dummy experimental testing and scientific research institutions or organizations, corresponding theoretical and practical data Less, reflecting China's research in the field is still weak.

In view of the current growth of China's current development and research status, military and civilian demand for high-performance flame retardant protective clothing, there is a necessary study and development of instrumental combustion fake people.

At the end of the 1980s, Alberta, Canada, also developed a dummy ldquo; pyroman rdquo; As shown in Figure 1-1 below, 110 heat flow sensors were installed on the surface of the dummy. The dummy and the sudden burning flame system are similar to the US military dummy system. After the six burners installed around the fake person ignited, the dispensed flame produced by the propane gas completely swallowed people. At the same time, a computer control data obtains the system to control the experiment, record, and store data from the sensor, calculate potential skin damage, ie, three degrees, three-degree burn area, respectively, the percentage of the total area of the body, and draw, printed out the results.

Switzerland, Japan and other countries have also developed second-generation ldquo; fire dummy rdquo; test device, collected data closer to test conditions under practical conditions, simulate special environment, improve testing of fire operations The exact degree of experimental results.
