Trampoline drop impact tester

Trampoline drop impact tester CX-8124B a Test principle: This device is based on ASTM F381 standards, prescribed by a weight and contour of the impact head on the trampoline frame portion of the liner is covered with a free fall impact, check trampoline lining After the pad is worn by the impact, if liner seams have split. Second, according to the standard: ASTM F381 clause6.2 & clause6.4 Third, test equipment consists of: This device is designed to cantilever support structure, size L1500 * W800 * H2000, columns and cantilever square tube production, the column on the side away from the cantilever are braces, used to improve the stiffness and stability of the whole rack. The bottom of the rack-mounted and floor with expansion bolts. Achieve free fall impact structure: fixed on the cantilever a reciprocating cylinder (cylinder erected fixed), on both sides of the cylinder fitted with the guide bar, which is connected via two guide rods above the cylinder piston rod into a flat A Overall, at the other end of the bottom plate B through another member connecting the two guide rods, plate B for fixing the impact head, the impact head weight plus the two guide rods and two webs total weight 23KG, cylinder The piston rod extends, will be lifting webs A, then head along the guide rod is moved upward together with the impact, the impact from the top of the cylinder head is used as a highly impact height, an air inlet cylinder quick exhaust valve is mounted, When the piston rod is retracted, the effect due to the rapid exhaust valve, the piston rod will be retracted at a rapid rate (this rate is greater than the impact of the head in a predetermined height do speed freefall lowest point) impact head complete impact on the trampoline pad at only gravity. Cantilever height adjustment: Since the height of the drop impact standards 305MM, this height is constant, and the height of the trampoline are different, highly functional movements cantilever design, the lifting device driven by a motor screw drive. Fourth, test methods and procedures:
