This machine specially test fire helmets impact resistance performance, can also do the anti-penetration properties test. Determination of fire helmets impact resistance performance, put the special head model with a good helmet (aluminium magnesium alloy materials) installed in the high sensitivity of the sensor, then use the 5kg hammer from 1 m height of impact, and the high sensitivity strength induction device detect the impact instantaneous force value to judge helmet shock absorption performance is good or bad.
Determination of the helmet antipenetration properties test, first fix the head model on the base, make head model,Steel cone and electrical contact display device to form a closed circuit, then put 3kg steel cone from 1 m height fall to puncture helmet, after puncture observation electrical contact display device. Judge helmet anti-penetration properties is good or bad.
