In the process of testing products, construction safety net manufacturers need to carry out shock resistance testing. The main methods and procedures are as follows:
1. Test equipment
(1) simulating the human shape sand bag: long 100cm, the bottom area is 2800 cm2, and the mass is (100 + 2).
(2) impact test frame: the opening size of the test frame is in accordance with the test network specifications, higher than 1.5m, and should be able to lift, drop and release simulated human shaped sand bags. The frame material should be rigid with carbon steel tube, with the structure reference six, but the plane of the test frame is parallel to the horizontal plane.
2. Test
The human shape sand bag is hung up so that the center of the sand bag is located in the center of the frame and the long side is parallel to the length of the dense mesh to the top of the frame. Then the test net is firmly attached to the test frame, and then the sand bag is lifted to release the sand bag at the bottom of the net from the net surface 1.5m.
3. Result representation
After being impacted by the dense mesh, the net body was not broken or swept through, and the edges and tether were not broken, indicating breaking.
