FXJ-1 Safety Helmet Impact Penetration Testing Mac

Product introductionThe machine is specific to test the impact resistance performance of safety helmet; it also can do the test of penetration resistance. When determine the impact resistance performance of safety helmets, set the special human head model which has worn the safety helmet well on the sensor of high sensitivity. Then start impacting, from the height of 1 meter with a hammer whose quality is 5kg and detect the instantaneous force values by using the force sensor of high-sensitivity so that we can determine that the impact absorption performance of safety helmet is good or bad. When determine the penetration resistance test of safety helmet, first fix the head model on the based seat so that the head modelsteel cone and the display device of electrical contact form a closed circuit. Then puncture the safety helmet from the height of 1 meter with an steel cone whose weight is 3kg, when after being punctured, observe the display device of electrical contact so that we can determine that the puncture resistance performance of safety helmet is good or bad.StandardsIS0 3873-1987, EN 397-1995, JIS T8131-2000, ANSI Z89.1-2003, GB/T 2811-2007 The main technological parameters1 Impact test Weight of steel hammer5kg+0.01kghammer head typeHemisphere typeDiameter: 96 mm.Weight of steel cone: 3+0.05KGcone angle 60ºradius of cone tip 0.5mmminimum length of cone stroke 40mm2 Height of falling hammer1m3 Maximum force sensor of impact test50000N4 The response range of frequency5-20 kHz
