Automobile Seat Headrest Fatigue and Durability Test Bench | Seat Headrest Strength and Durability Test Bench
The automotive seat headrest fatigue and durability test bench and the seat headrest strength and durability test bench are important equipment for testing the performance of automotive seat headrests.
Main uses
It is used to test the fatigue and durability of automotive seat headrests during long - term use, simulate the actions of the headrest under different adjustment times and usage frequencies to evaluate its service life.
According to relevant standards, such as GB 11550 - 2009, GB 15083 - 2024, etc., test the strength of automotive seat headrests, check the bearing capacity and deformation of the headrest when subjected to forces of different directions and magnitudes, and ensure that it can provide effective protection for drivers and passengers in case of vehicle collisions and other emergencies.
Structural composition
Loading system : It is loaded by an electric servo cylinder, which can generate accurate loading forces and simulate various forces that the headrest bears in actual use, such as vertical pressure and horizontal pulling force.
Displacement measurement system : It is equipped with a high - precision displacement sensor to measure the displacement change of the headrest during the loading process in real - time to evaluate its deformation degree. The displacement measurement accuracy can reach ±0.2mm.
Control system : It adopts a computer control system to realize the automatic control of the test process and data acquisition. You can set test parameters, control the loading force and displacement, display test data and curves in real - time, and automatically generate test reports.
Technical parameters
Load measurement range : Generally, it is 40N - 2000N to meet the testing requirements of different types and specifications of automotive seat headrests.
Loading frequency range : Usually, it can be adjusted arbitrarily between 0.5Hz - 10Hz, which can simulate different usage frequencies and working conditions.
Test stroke : The displacement is generally 0 - 400mm, and the stroke of the electric cylinder is 0 - 500mm, which can meet the test requirements of the headrest in different adjustment positions and deformation ranges.
Test methods
Fatigue and durability test : Move by setting a certain loading force, frequency and number of cycles until the set number of cycles is reached or the headrest shows fatigue failure phenomena. Record the data and the state changes of the headrest during the test process.
Strength test : According to relevant standards, apply static forces of different directions and magnitudes to the seat headrest, such as applying pressure perpendicular to the backrest or horizontal pulling force to the headrest, measure the deformation, displacement and the force that the headrest can bear during the force - bearing process, and judge whether it meets the strength requirements.
