Helmet Acceleration Impact Puncture Tester Motorcycle Helmet Impact Testing Machine
1. Product Description
Application: GB2812 standard helmet acceleration impact puncture tester is suitable for helmet impact performance test, and is used to judge the impact resistance of helmets. This machine adopts HOTOTECH's self-developed upper computer control system, automatically lifts the fixture to a predetermined height, and displays the height in real time, and displays the acceleration Peak value, test curve, impact speed, action time, impact energy, etc. in real time on the operation interface. At the same time, it can meet the puncture test, and only needs to replace the fixture, which is easy to operate.

3. Impact Test Steps
a) Determine the headform to be used according to the requirements of Appendix A
b) Wear the sample on the headform according to the manufacturer's instructions
c) Install the acceleration sensor in the ball head and connect it to the sliding arm through the ball arm
d) Install the flat shoe and make the helmet body just contact with the flat shoe
e) Adjust the free fall distance from the contact point to the flat shoe to (1380±5) mm
f) Release the headform and record the peak acceleration and cumulative time
g) Select another point of the sample to just contact with the flat shoe
h) Repeat (e) to (f)
i) Install the hemispherical shoe and make the helmet body just contact with the hemispherical shoe
j) Adjust the free fall distance from the contact point to the flat shoe to (1020±5) mm
k) Release the headform and record the peak acceleration and cumulative time
l) Select another point of the sample that just touches the hemisphere
m) Repeat j)~k)

Main machine performance features:
1. Servo motor, servo controller and its supporting control unit are used as drive components, and the motor has a long life.
2. Hollow gear reduction system is used, which has low power consumption, low noise, high efficiency and strong reliability.
3. Zhongtai data acquisition card is used to keep the accuracy of the test machine unchanged for a long time.
4. The direct plug-in transmission device is used to achieve high positioning accuracy, long life, low friction, high-speed operation and forward and reverse rotation, so that the whole machine can run horizontally,
displacement, and speed accuracy are greatly improved.
5. It has a position limit function, so that some position limit requirements The test required is safer and faster.
6. Extremely wide measurement range, applicable to the standards of multiple countries.
7. Adopting the integrated design principle, no matter what the configuration of the host is, modify the corresponding computer parameters (parameters can be permanently retained),
no circuit adjustment is required.
8. High-precision return positioning function, no matter what the return speed is, it can accurately return to the starting position, speed up the test speed, and improve work efficiency.
9. Common parameter memory function, such as test speed, etc., so that it is in this parameter state as soon as it is turned on, which greatly facilitates users.
10. Flexible and convenient operation, with two working modes of constant movement and inching movement, users can freely set it conveniently to adapt to different occasions or habits.
11. It has multiple protection functions: adjustable upper and lower limit protection, emergency stop protection, etc.
