[0019] Example 1
[0020] The material impact test device of pneumatic imitator (cannon) projectile is mainly composed of air compressor (1), computer (3), solenoid valve (4) equipped with inching switch (4), magnet (5), photoelectric tachometer (7) , Launch tube (8), impact bomb (9), bracket (10), etc. The air compressor (1) is connected with the solenoid valve (4) and the launch tube (8) through the plastic hose (2) to form the compressed air circuit of the impact test device. At the center of the launch tube (8) where the photoelectric speedometer (7) is installed, two small holes with a diameter of about 2mm are symmetrically drilled to ensure that the light from the photoelectric speedometer (7) can pass through the launch tube (8). In order to ensure accurate measurement of the speed and energy of the impact bomb (9), the minimum distance from the center of the small hole to the launch tube (8) is half the thickness of the photoelectric tachometer (7), and the maximum dis...

[0022] Example 2
[0023] figure 2 In order to carry out material impact test, the calculation and statistics table of impact bomb energy displayed by computer. The impact bomb passes the photoelectric tachometer, and the computer can measure the blocking time of the impact bomb in real time and calculate the speed of the impact bomb according to the length of the impact bomb. At the same time, the impact energy of the impact bomb is automatically calculated according to the mass of the impact bomb and displayed on the computer.
