Car seat fatigue tester

1. Product Overview

The Car Seat Fatigue Tester is a precision testing system designed to evaluate the long-term durability and fatigue performance of automotive seat foam and liner materials. By simulating repeated compression and load conditions, the tester ensures that seats meet safety, comfort, and quality requirements over extended use. The system is widely used by automotive OEMs, seat manufacturers, and testing laboratories for R&D, performance verification, and quality control.

2. Product Features

Simulates real-world seat loading conditions with adjustable impact forces up to 750 N or higher.

Supports reciprocating compression with adjustable frequency, capable of 75 cycles per minute or more.

Configurable compression stroke (typically 150–180 mm) to simulate a range of load conditions.

Disc diameter customizable according to seat design to ensure accurate and reliable testing.

Programmable number of test cycles to meet specific fatigue testing requirements.

Advanced display and control system provides real-time monitoring of load, displacement, and test duration.

Equipped with safety features including overload protection and emergency stop for reliable operation.

Durable mechanical structure ensures stable and repeatable fatigue testing over long-term operation.

3. Applicable Standards

GB/T 18941-2003 – Test method for foam polymer materials used in car seats, including reciprocating compression testing.

ISO 3385-1989 – International standard for compression fatigue testing of soft foam polymer materials.

QC/T 56-93 – Chinese automotive industry standard for performance testing of car seat liner materials, including fatigue testing.
