Seat belt overall dynamic load standard specifies test requirements and methods
2023-06-19 08:12:04
Test requirements: When the length of the safety rope (including the open buffer) is less than 0.5m, the suspension does not simulate the impact of the hip loop. The sensor is connected in series between the connector and the hanging point during testing. When the falling impact test of a falling suspension belt including a safety rope and a self-locking device is performed, the sensor assembly should be as small as possible so as not to affect the operation of the self-locking device.
Test method: Dynamic load test of falling suspension belt with safety rope only: According to the product description, wear the safety belt on the simulated person, and simulate the connection between the head's head lifting ring and the releaser to increase the height of the simulated person to 1 m above the suspension point. Ensure that the horizontal distance from the suspension point to the release point is less than 300mm; make a mark at the buckle and buckle frame passing through the adjustment buckle; release the dummy and start timing; after 5min, check the seatbelt condition and record the test result; A new seatbelt, according to the product description will wear the seatbelt on the simulated person, simulate the human hip rings and the release device to connect, lift the head of the simulation of the suspension point to the level of the suspension, to ensure that the horizontal distance from the suspension point to the release point is less than 300mm; release Simulate the person and start the timing; after 5 minutes, measure and record the slippage of the deviation mark, observe and record the condition of the seatbelt.
Fall load suspension belt with safety rope and self-locking device Dynamic load test: wear the seat belt on the dummy according to the product description, simulate the connection between the head lifting ring and the release device, and lift the dummy to the self-locking device to be free on the guide rail Slide to ensure that the horizontal distance from the suspension point to the release point is less than 300mm; make a mark at the buckle and buckle frame passing through the adjustment buckle; release the dummy and start timing; after 5min, measure and record the deviation of the deviation mark, Observe and record seat belt conditions; repeat the above steps with the same set of seat belts; replace with a new seat belt and wear seat belts on the simulated person according to the product instructions. Simulate human hip rings and releasers to connect and lift the head of the simulator. The self-locking device can slide freely on the guide rail to ensure that the horizontal distance from the suspension point to the release point is less than 300mm; repeat the above steps; repeat the new seatbelt testing process with the same seatbelt.
Fall load suspension belt with speed difference automatic loader dynamic load test: According to the product description, the seat belt is worn on the simulated person, the head of the simulated person is connected with the release device, and the simulated person is lifted to the center of gravity higher than the suspension point by 1m to ensure the suspension. The horizontal distance from the point to the release point is less than 300mm; the mark is made at the buckle and buckle frame passing through the adjustment buckle; the dummy is released and the timing is started; after 5 minutes, the slippage of the deviation mark is measured and recorded, and the safety is observed and recorded With the situation.
