The Hydraulic Continuous Fatigue and Tensile Testing Machine is a dual-function electro-hydraulic servo test system designed to perform either tensile testing or continuous fatigue testing independently. The system is engineered for high-load, long-cycle durability evaluation of components and assemblies, particularly in automotive seating and safety-related applications. Each test station operates independently and is driven by a centralized hydraulic power unit with a dedicated PC-based control and data acquisition system.

Application

This testing machine is widely used for mechanical performance verification of components subjected to repeated loading or static tensile forces, including but not limited to:

Automotive seats and seat structures

Seat rails, seat frames, and adjustment mechanisms

Seat belts, anchors, and fastening components

Interior structural brackets and welded assemblies

Metal and composite structural components

Rubber, polymer, and elastomer fatigue specimens

It is suitable for both laboratory qualification testing and production quality validation in automotive, transportation, and component manufacturing industries.

Standards

The system is designed to meet or support the requirements of the following international and industry-related standards (test methods configurable):

(1) ISO 7500-1 – Metallic materials — Verification of static uniaxial testing machines

(2) ISO 13003 – Fibre-reinforced plastics — Fatigue testing under cyclic loading

(3) ASTM E466 – Standard Practice for Conducting Force Controlled Constant Amplitude Axial Fatigue Tests
