Car seat belt anchorage strength testing machine (9-axis)

Car seat belt anchorage strength testing machine (9-axis) CX-7105 Description: First Use: The test equipment according to user requirements and associated test standard design for testing a variety of automotive seat frames, car seat head pillow, car seat belt and car seat assembly under certain experimental conditions, static and structural strength and the safety and reliability of the finished product under dynamic conditions; rear seats used to evaluate the production process and product installation, inspect welding molding each weld point, all the joints and locking mechanism in the role of being a certain direction and a certain force can withstand the force, in order to determine the strength of the seat frame and finished seat and the corresponding amount of deformation, and automatically record the test by computer various values ??of power, strength, displacement and deformation amount and automatically form a test curve and test reports. Reference Standard: GB 15083 a 2006 automotive seat systems - Strength requirements and test methods GB 14167 a 2006 car safety belt installation position of the fixed point of strength requirements and test methods for strength GB / T 13057-2003 passenger seat and the vehicle parts Strength and ECE R17, ECE R80 and ECE R14, FMVSS207 two main test items and test methods: 1. Automotive seat systems Strength test: the seat according to the design mounted on a test bench simulation of the body, if no suitable focus point on the seat, allowing local reinforcement at the site of the pilot project does not involve the upper end of the reinforcing bars are fixed in the same root horizontal beam, and the other end is fixed to the seat as the front link mechanism regulating portions, the horizontal beam centroid height should be the same height as the seat, the seat through the centroid, respectively, each of the forward and backward along the horizontal exert considerable the seat assembly 20 times the force of gravity. Assembly and the body can not be separated from the body. For adjustable seat, adjusting means test should allow adjusting the position of the seat to keep the original back seat if there is time to prevent the structure of the seat back, only forward load; for adjustable seat, the seat should be separately Chair transferred to the final position and angle of the backrest is locked in position design or an equivalent design angular position; when folding seat test, the stopper should be pre-fixed on the forward seat by the seat hinge or folded portion of the center of mass, is applied along the horizontal direction corresponds to the forward or folded portion of the seat hinge 20 times the force of gravity; to the seat post, the seat hinge or folded portion through the centroid, is applied along the horizontal direction corresponds to rearward hinged or folding portion of the seat 8 times the force of gravity. Gradually loaded as required to the specified value and the value remains on more than 0.2s, the loading speed of not more than 5mm / min; relative failure deformation when the test is completed or institution occurs, the computer automatically stop the test and automatically record the relevant parameters. 2. The car seat belt to install a fixed point of strength tests: the seat according to the design mounted on a test bench simulation of the body, (1) the seat shall be equipped with a complete design and adjusted to a reference position; a direction parallel to the vehicle longitudinal center plane and and 10 ± 5 ° to the horizontal direction, to spend time loading applied load forward under the body module load reaches a predetermined value in the 60s, and for at least 0.2s; for Class Ⅰ fixed point seat belt installation test, will Good seat belt mounting sleeve on the lower body module, according to test requirements specified 22300 ± 220N load is applied to the human body module, but M2, M3 and N category class cars car rear seat is 2940 ± 200N load is applied; for Type Ⅱ fixed point seat belt installation test, a good belt mounting sleeve on the lower body and upper body module module, according to test requirements set for both at the same time each body module 13500 ± 200N load is applied, but the M2, M3 class N class car and car rear seats up and down the two modules is 2940 ± 200N load is applied; (2) at the same time through the centroid of the seat during the test, in the longitudinal direction of the seat applied horizontally forward 20 times the weight of the load, but the M2, M3 class N class car and car backseats P is applied load, and for at least 0.5s; P load is determined as follows: P = (735N + 1 seater seat weight) × 4; occurs when the end of the trial, or institution relative deformation failure, the computer automatically stop the test and automatically record the relevant parameters.
