Helmet Surface Protrusion Shear and Friction Tester/ helmet surface friction testing machine/ Helmet surface protrusion shear tester
In the realm of protective headgear, a helmet's primary role is to absorb and deflect impact forces to safeguard the wearer's head. However, the external surface of a helmet plays a crucial, yet often overlooked, role in rotational injury prevention. When a helmet strikes a surface at an angle, any protrusions or high-friction areas on its exterior can create rotational forces that transmit harmful shear and torsion to the head and brain. This is precisely why the Helmet Surface Protrusion Shear and Friction Tester is an indispensable tool in modern helmet safety assessment.
Purpose
The Shear Force and Friction Tester for Helmet Surface Protrusions is mainly used to test the shear force and friction performance of the protrusion structures on the helmet surface.
Main Uses
Produced according to helmet related standards, it is mainly used to test the shear force and friction performance of the surface raised structure of motorcycle helmets and electric vehicle helmets. Widely used in various helmets related production, scientific research, quality supervision and testing units.
Main features
1. PLC touch screen control.
2. Horizontally oriented carrier with exchangeable installation of sandpaper and cutter.
3、Head type can be rotated 360.
4、Equipped with professional speed measuring tooling.
Main indicators
1. friction sandpaper: 300mm-303mm long, grade 80 aluminum oxide coated sandpaper.
2. steel cutter: 6mm high, 25mm wide, the top edge of the cutter is chamfered with a radius of 1mm.
3、Impact weight: 15kg-15.5kg
4、Weight fall height: 0-1000mm.
5、Pre-loaded weight: 400N-410N.
6、Sensor range: 0-120mm.
7、Power supply of the instrument: 220V 50Hz.
