Seat belt dynamic load standard test method

First, the dynamic load test of the lace 1. According to the product description, the strap is worn on the simulated human body, and the simulated human is suspended on the hanging point of the suspension mechanism;

2. Connect one end of the wire rope to the connector of the tie, and connect the other end to the hanging point of the test bench. The simulator suspends the person to the center of gravity higher than the hanging point of the test bench by 1m and the horizontal distance is within 0.3m.

3. Release the simulated person and observe the peak impact force. The value is between (6 ± 0.3) kN. The test is considered as valid;

4, check the situation, uninstall;

5, for a pair of straps, suspension simulation of human hip rings, repeat 1 to 4 items;

Second, the connector dynamic load test 1, the end of the wire rope is connected to the connector, the other end is connected to 100 ± 1kg shovel;

2. Connect the other end of the connector to the hanging point of the test bench and lift the shovel to a certain height.

3. Release the shovel and observe the peak impact force. The value is between (6 ± 0.3) kN. The test is considered valid;

4, check the connector, uninstall.

Third, self-locking dynamic load test 1, the end of the wire rope is connected to the self-locking device, the other end is connected to the 100 ± 1kg iron file;

2. Lift the shovel to a certain height, the horizontal distance between the shovel and the self-locking device is less than 0.3m;

3. Release the shovel and observe the peak impact force. The value is between (6 ± 0.3) kN. The test is considered valid;

4, repeat 2,3 operations;

5, check the situation of self-locking device, measure the locking distance, uninstall;

6. Use the same self-locking device and use 40±0.5kg iron rake, repeat 1~4 items. This article is the original article of Qingdao Zhongbang Instrument Co., Ltd. If you need to reprint, you must add the source of the description. Reproduce the piracy without permission. !
