Gas Spring Testing Machine

Servo test bench for lift gas springs, used for static force characteristic, speed curve and cyclic durability fatigue test

Product Overview

This gas spring testing machine adopts high-precision servo reciprocating drive system, designed for nitrogen-filled gas springs widely used in automotive tailgates, hoods, furniture, medical beds and equipment covers. It supports static force test, speed characteristic test, stretching and compression curve test, and long-cycle fatigue durability test. The equipment can detect output force, damping force, idle stroke, hysteresis and air leakage of gas springs. It automatically collects force and displacement data, generates force-stroke curves and force-speed characteristic curves, and records force attenuation after repeated cycles. Universal adjustable fixtures adapt to different installation lengths and connection ends. It is widely used in gas spring product development, sample verification, incoming inspection and finished product quality audit.

Applicable International Standards

The system is designed to comply with the following recognized testing standards:

ISO 11901-1 — Tools for pressing — Gas springs — General specifications
EN 16955 — Hardware for furniture — Gas springs for seating height adjustment
ISO 7500-1 — Verification of static uniaxial testing machines
ISO 5893 — Specification for constant-rate traverse test equipment

Note: Specific compliance depends on model configuration, force sensor selection and customized fixture design. Customized fixtures and test schemes for extra testing standards are available upon request.
