Car seat fatigue tester
Applicable standards:
GB/T 18941-2003 "Test method of foam polymer materials for car seats" : This standard specifies the test method of foam polymer materials for car seats, including reciprocating compression test, etc., which is suitable for the fatigue performance test of foam materials for car seats.
ISO 3385-1989: This is an international standard that specifies the compression fatigue test method for soft foam polymer materials, which is also applicable to the fatigue performance test of automotive seat foam materials.
QC/T 56-93 "Performance Test method of Car Seat Liner Material" : This standard is the industry standard of China's automotive industry, which specifies the performance test method of car seat liner material, including fatigue test.
Main parameters:
Loading impact force: The tester usually has a certain range of loading impact force, which is used to simulate the load borne by the seat in actual use. For example, some models of testers can load impact forces up to 750N or higher.
Reciprocating compression frequency: The reciprocating compression frequency of the tester indicates the number of compression-release cycles performed per unit time. This parameter can usually be adjusted within a certain range to suit different test requirements. For example, some models of testers can compress up to 75 times/minute or more.
Reciprocating compression stroke: The reciprocating compression stroke refers to the maximum distance the tester moves during compression. This parameter determines the range of loads that the tester can simulate. In general, reciprocating compression stroke between 150mm and 180mm is more common.
Disc diameter: The disc is a component used to apply loads, and its diameter can affect the accuracy and reliability of test results. The diameter of the pressure disc may vary from model to model.
Number of tests: The tester can usually set the number of tests to achieve a predetermined test cycle. The number of tests should be set according to the specific test criteria and seat type.
Display and control: Modern car seat fatigue testers are usually equipped with advanced display and control systems, which can display various data in the test process in real time, such as load, displacement, time, etc., and can accurately control the test parameters.
Safety performance: The tester should have perfect safety protection measures, such as overload protection, emergency stop button, etc., to ensure the safety and reliability of the test process.
