The Compression Fatigue Testing Machine is a mechanical testing device designed to evaluate the fatigue performance of materials or components under repeated compressive loads. It simulates the cyclic forces that a specimen would experience in real-life applications, helping assess durability, structural integrity, and long-term reliability.
Standard
(1)YY/T 0959-2014 (China): Specifies compression fatigue testing protocols for intervertebral fusion devices, including load ratios, frequency, and failure criteria.
(2)ASTM F2077-17 (International): Defines methodologies for evaluating the fatigue strength of intervertebral body fusion devices under compressive loading.
(3)ISO 12189-1: Additional compliance for mechanical testing of spinal implant components.
Application
The Compression Fatigue Testing Machine is used to evaluate the durability and fatigue resistance of materials, mechanical components, and structural parts under repeated compressive loads. It helps manufacturers and researchers predict long-term performance, optimize designs, and ensure compliance with mechanical testing standards.
