Brief introduction: Safety helmet impact testing machine According to new national standard GB/T 2812-2006 safety helmet helmet test method development, used to detect the helmet impact testing machine shock absorption performance and durability performance, high degree of automation, convenient operation, widely used in the helmet production enterprises, the quality inspection institutions and testing station construction. Features: 1. The impact hammer and hammer replacement operation is simple. 2. The helmet impact tester platform: able to control the suspension and the release of drop hammer impact hammer, puncture. 3. The helmet impact tester base: has the impact strength, strong force transducer installation. 4. The helmet impact testing machine electricity display device: when the circuit to form a closed loop, can signal, said piercing cone have contact mode. 5. The impact of professional high-precision sensors, frequency corresponding minimum 5 KHZ, force sensor, dynamic range is 2 t, precision is + / - 2.0%. 6.1 #, 2 # aluminum silicon alloy test with head each one. In line with the GB/T 2812-2006, as stated in appendix A. 7. Helmet impact testing machine control box, position can be adjusted according to user's preferences, easy to use. 8. Helmet impact testing machine According to the type of the helmet drop height adjustment. 9. Helmet impact tester LED digital display, automatic save the most value Technical indicators: 1. The impact hammer Drop hammer impact: the quality of 5-5.01 kg, hammer head hemispherical, 96 mm in diameter, material of 45 # steel. Puncture hammer: quality for 3-3.05 kg, puncture part of the cone Angle 60 °, cone tip 1 mm in diameter, length of 40 mm, maximum diameter 28 mm, hardness HRC45. 2. The helmet impact tester strain sensors: Measuring range 0-20 kn, frequency corresponding minimum 5 KHZ, dynamic force sensor, accurate to 1 n. (may, by domestic only has 5000 hz dynamic sensor measurement qualification of institute of metrology measurement appraisal, ensure the data accurate and reliable) 3. Drop height: 1000 mm. 4. The working power supply: AC220V, 50 hz 5. Put the position: the ground
