HOTOTECH ECE R17 Car Seat Tester Headrest Backrest Static Strength Testing Bench Automotive Carseat Restraint Rig

Product DescriptionThe three-position headrest and backrest static strength testing bench for automotive seats is primarily used to test the static strength of seat headrests and backrests. This testing machine is suitable for the following scenarios: evaluation tests for the static strength of seat headrests and backrests, new design, process changes, material changes, source verification, and product quality inspections. Applied CodeECE R17 provisions on strength of automotive seat headrests and seat backrests; GB15083-2019"Strength requirements and test methods for automotive seats, seat fasteners and headrests".Technical Parameter Equipment sizeMain test bench: (3500 x 2000 x 2200) mm;Control cabinet:(600 x 600 x 1800) mm;Distribution cabinet: (800 x 600 x 1000) mm;Equipment power supplysingle phase AC 220V, 50Hz, 5KW.Nine servo electric cylinders, six headrest backrest static strengthSix headrest backrest static strength servo electric cylindersTravel 600mm, displacement accuracy±1%, displacement resolution: 0.01mm;Maximum thrust 2kN, accuracy: ±1%, resolution: 0.1N;The loading position is above point H 290±0.25mmLoad sensorLoad: 2KNQuantity:6Accuracy:±1%Optical code displacement sensor (optical encoder with servo motor)Quantity: 9 Linear accuracy0.05%F·S Reproducibility0.1%Sampling frequency 2KHzThe measurement accuracybetter than ±1%.Control accuracy better than ±1%.Characteristics1,The test bench is mainly composed of a cast iron base platform for seat installation, a static strength test frame for headrest backrest, an H-point alignment device, a load sensor, a servo motor and driver, an electrical control and acquisition system, and test software.2,Load full range without grading, loading speed adjustable.3,Controlled by servo electric cylinders, high-performance real-time automatic gain adjustment, which can automatically adjust the gain according to changes in load inertia, in conjunction with adaptive filters. The system can automatically adjust the gain from low rigidity to high rigidity.4,The measurement control system uses a high-performance motion control card from National Instruments (NI) as the core component, with function units templated and standardized, featuring flexible configuration, strong interchangeability, and easy after-sales service;5,Cast iron platform:The flatness tolerance of this platform is grade 2 as specified in JB/T7974-1999. The bottom platform is a cast iron platform with longitudinal T-shaped groove.The platform is cast with high strength cast iron HT250. The platform has been demagnetized and stabilized. The platform has high precision and good wear resistance.6,The test frame for the static strength of headrests consists of the main column, transverse movement device of the column, longitudinal movement device of the column, horizontal support, vertical movement device of the horizontal support, swinging support, loading mechanism, up-and-down movement device of the headrest loading cylinder, headrest loading servo electric cylinder, backrest loading servo electric cylinder, head mold, back mold, high-precision load sensor, etc. Our Services
