A trench is a trench dug along the front of a position for combat, and the combatants are in the trench to attack the external enemy. In modern warfare, trenches are still widely used on the battlefield. They can not only efficiently resist the attack of traditional damage elements such as ammunition fragments, but also their underground trench structure can greatly reduce the intensity of explosion shock waves after they arrive.

Thermobaric explosives as warheads have been used more and more in actual combat. Thermobaric explosives have the characteristics of both high explosives and fuel-air explosives. Said to be a fuel-rich high explosive. Its detonation velocity is generally 3-4 kilometers per second, which is much lower than that of high explosives (typical value is 8 kilometers per second); at the same time, a large amount of oxygen is absorbed from the surrounding air during the detonation process, resulting in a lack of oxygen. environment. The most important point is that powders of aluminum, boron, silicon, titanium, magnesium, zirconium and other substances are added to the thermobaric explosive. These powder beams ignite and release a large amount of energy in a heated state, which greatly enhances the thermobaric explosive. Thermal and pressure effects. Strong shock waves are formed during the explosion, which can cause serious damage to personnel, fortifications, and equipment; the thermal effect of thermobaric explosives can burn the oxygen in the air, causing temporary hypoxia in the explosion point area.

Therefore, a test device and method for the distribution of damage elements of thermobaric explosives are needed to simulate the damage characteristics and distribution rules of thermobaric explosive explosions in trenches, and then compare Analyze the protection performance of different types of trenches against thermobaric explosive explosion damage elements, so as to guide the optimization of trench protection structures, improve the battlefield survivability of soldiers, provide guidance for practical applications in war, and provide experience for subsequent similar experiments. Provide a data basis for scientific research-related numerical simulations.

and dividing the installation positions by taking the explosion point as the circle center and r as the radius, wherein more than two installation positions are arranged.

10. The warm-pressing explosive damage element distribution test method according to claim 9, characterized in that;

judging the installation position;

if the mounting position is not shielded from the explosion point, a temperature measuring sensor (202 a) is arranged at the mounting position;

if the mounting position is shielded from the explosion point, the mounting position is provided with an infrared temperature measurement sensor (202 b);

the temperature sensors (202 a) and the infrared temperature sensors (202 b) correspond to the temperature data one by one and are stored through the second data acquisition instrument (201 d).
