Content

The Large Spring Fatigue Testing Machine is specially designed for fatigue life and durability testing of large springs and elastic components, including compression springs, tension springs, shock absorber springs, locomotive springs, valve springs, gas springs, air springs, wave springs, and disc springs.

Applicable Standards

JB/T 7796-2005 — Spring Tension and Compression Testing Machine

GB/T 1239.2 — Cold Coiled Helical Compression Springs — Technical Requirements

GB/T 19844 — Springs — Technical Specifications

GB/T 2611 — General Requirements for Testing Machines

GB/T 16825.1 — Verification of Static Uniaxial Testing Machines

JJG 139 — Verification Regulation of Tension, Compression and Universal Testing Machines

ISO 10243 — Tool Dies — Compression Springs — Specifications

Application

The Large Spring Fatigue Testing Machine is mainly used for fatigue life testing and durability evaluation of various large-scale elastic components, including tension and compression springs, shock absorber springs, locomotive springs, valve springs, gas springs, air springs, wave springs, disc springs, and other metal components.

The machine can simulate the vertical working conditions of specimens and perform high-cycle fatigue tests (over one million cycles) as well as tension and compression tests. Equipped with dedicated testing software, it integrates test control, data acquisition, and data processing functions to analyze and evaluate product performance and service behavior after testing under specified conditions.

It is widely used in spring manufacturing, automotive components, shock absorber production, railway equipment, machinery industries, and research laboratories for fatigue life assessment, reliability verification, and quality inspection.
