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 :
1.The force value range: 0 ~ 2000N, accuracy 1%.
2.The displacement range: 0-500mm, precision 0.1mm.
3.The timing range: 0-99min, precision 0.1s.
4. 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.
5.The beam speed: 0-500mm/min when no load, infinitely variable speed can be adjusted. Easy and quick adjustment of position according to helmet. During the test, Class A 113N/min and Class B 75N/min were automatically switched according to the test conditions.
6.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.
Applicable standards : GB811-2010
