Moves Straight Up and Down Motorcycle Helmet Wearable Device
Strength Tester
Main purpose
According to motorcycle helmet gb811-2010 production, mainly used
to test motorcycle helmet wearing device strength performance.
Widely used in motorcycle helmet related production, scientific
research, quality supervision and inspection units.
Main features
1. The main structure of single-column structure moves straight up
and down.
2. The large strap stretch stroke, stretching up to 500mm, to
overcome the lower leg under the force from the adjustment buckle
slippage caused by the deformation of the drawbacks.
3. It can be set the initial load, the initial load to
automatically collect deformation, without manual manual reset.
4. The test process touch screen + PLC + special test program
control. The program does not require manual adjustment of the
speed of automatic control, the program automatically adjusts
according to the test conditions, automatic test data and results
of judgment and processing.
5.Test and maintain the test program automatic closed-loop control,
automatic 30S or 120S fixed force value to maintain. No need to
adjust manually according to the change of force value.
6. Real-time display of force value, time, displacement,
deformation, speed, test curve, etc. during the test.
Main indicators
| The force value range | 0 ~ 2000N, accuracy 1%. |
| The displacement range | 0-500mm, precision 0.1mm. |
| The timing range | 0-99min, precision 0.1s. |
| Man-made chin | The diameter of the rigid shaft is 25mm, the distance between the
two axes is 75mm, and the shaft length is 50mm. |
| The beam speed | 0-500mm/min when no load, infinitely variable speed can be
adjusted. Easy and quick adjustment of position according to
helmet. |
| Class A and Class B | During the test,Class A 113N/min and Class B 75N/min were
automatically switched according to the test conditions. |
| Working power | AC220V, 50Hz. |
Results of the decision
According to the provisions of GB811-2010 Motorcycle Member Helmet,
the strength performance of the helmet wearing device should meet
there shall be no elongation of more than 25mm or tearing of the
laces, loosening of the connectors, and loosening of the buckles.
