The Car Seat Fatigue Tester is a dedicated durability testing system used to evaluate the long-term fatigue performance of automotive seat foam, cushion assemblies, and liner materials under repeated compression loading.
By simulating continuous seating and load cycles experienced during real vehicle use, the tester assesses changes in mechanical properties, deformation behavior, and structural stability over extended service life.
Application
(1) Fatigue durability testing of automotive seat cushion foam.
(2) Reciprocating compression testing of seat liner and padding materials.
(3) Long-term performance evaluation of complete seat cushion assemblies.
(4) Compression fatigue testing of polyurethane foam used in automotive seating.
(5) Comfort durability verification under repeated seating load conditions.
(6) Comparison testing of different foam formulations, densities, and structures.
(7) R&D validation of newly developed seat foam and cushion materials.
(8) Quality consistency inspection for seat foam during mass production.
(9) Incoming inspection and supplier evaluation of seat foam and liner materials.
(10) OEM internal certification and compliance testing for seat fatigue performance.
(11) Failure analysis and durability improvement testing after material optimization.
Standards
(1) GB/T 18941-2003 – Test methods for foam polymer materials used in automotive seats, including reciprocating compression fatigue testing.
(2) ISO 3385 – Flexible cellular polymeric materials – Determination of fatigue by constant-force pounding.
(3) QC/T 56-93 – Automotive industry standard for performance testing of car seat liner materials, including fatigue testing.
(4) ASTM D3574 – Standard test methods for flexible cellular materials (foam fatigue-related methods).
Features
(1) Simulates real seating load conditions through controlled reciprocating compression.
(2) Adjustable impact force to meet different seat and foam test requirements.
(3) Variable compression frequency supports long-term fatigue simulation.
(4) Programmable test cycles allow precise control of fatigue duration.
(5) Configurable compression stroke accommodates different seat structures.
(6) Disc diameter can be customized to match actual seat contact conditions.
(7) Real-time monitoring of load, displacement, and test time ensures accurate evaluation.
(8) Robust mechanical structure designed for continuous long-duration operation.
(9) Integrated safety protection including overload protection and emergency stop.
