[0003] Since the performance of the seat belt is concentrated with a variety of performances, and the trigger time of some performances is sequential, if a single performance test device is used to test the corresponding performance of the seat belt, on the one hand, the measured results may be interfered by other performance devices, resulting in Test error, on the other hand, different performances cannot be measured by the same seat belt system, and the process error of different seat belts will affect the analysis accuracy of the overall performance of the seat belt

The invention provides a safety belt multiple-performance component test device and test method. The test device comprises a safety belt installation support arranged on an installation bottom board, a safety belt D ring, a steering mechanism, a safety belt, an extensometer, a pull wire displacement sensor, a safety belt coiler, a damper, a loading member, a safety belt D ring installation block and a safety belt coiler installation block. One end of the safety belt is wound to the safety belt coiler, and the other end thereof passes through the safety belt D ring and steering mechanism in sequence and is connected with a movable shaft of the damper; the bottom end of the damper is provided with a locking pin for locking the movable shaft; and the safety belts at the two sides of the safety belt D ring are provided with a first braided belt force sensor and a second braided belt force sensor respectively. The test method is used for carrying out safety belt multiple-performance component test. The test device and test method can test multiple performances of pre-tightening force, limitation force, characteristics of the coiler, elongation percentage of the braided belt and D ring friction force and the like of the safety belt simultaneously, thereby saving test cost and improving test accuracy.
Description
technical field [0001] The invention belongs to the field of testing devices, and in particular relates to a testing device and a testing method for multi-performance components of a safety belt. Background technique [0002] Seat belts are essential safety aids for passenger cars, and are important equipment for maintaining occupant safety during vehicle collisions. At present, the most common seat belt used in passenger cars is a three-point seat belt. Generally, the retractor is located at the rear or side of the occupant, and the D-ring is fixed at the side of the occupant's head. The D-ring can wrap around the fixing screw within a certain range. turn inside. The seat belt webbing is led out from the retractor outlet and passes through the D-ring, and after passing through the D-ring, the webbing extends to the occupant's chest, preventing the occupant from moving forward during a vehicle collision. The seat belt with the preload force limit function will roll the sea...
