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. |
Principle:
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.
