The Bone Plate Four-Point Bending Fatigue Testing Machine is a specialized device used to evaluate the fatigue performance and mechanical strength of orthopedic bone plates. It applies cyclic four-point bending loads to simulate physiological conditions, allowing assessment of the plate’s durability, bending strength, and failure characteristics under repeated stress.
Standards
(1)YY/T 1503
(2)ASTM F382
These standards specify the testing methods for the bending fatigue performance of metallic bone plates. They provide evaluation methods for different designs of bone plates. Fatigue tests are conducted under cyclic loading at a frequency of 5 Hz, with R = 0.1. for 1 million cycles or until specimen failure.
The M series electromagnetic testing system provides precise sinusoidal load control and offers comprehensive test fixtures (different sizes, contoured rollers, etc.) to accommodate specimens of various dimensions. The system also provides accurate and effective testing procedures (SOPs) to support mechanical performance analysis of metal bone plates or comparison of different bone plate designs.
Application
The Bone Plate Four-Point Bending Fatigue Testing Machine is designed to evaluate the mechanical durability and structural performance of orthopedic bone plates under repeated bending loads. Typical applications include:
Orthopedic implant testing: Assess bending strength, stiffness, and fatigue life of bone plates.
Quality control: Ensure consistent mechanical performance of bone plates during production.
Research and development: Optimize design, material, and geometry of bone plates for enhanced fatigue resistance.
Standards compliance: Perform tests according to ISO 9585. ASTM F382. and other relevant international guidelines.
This machine helps verify that bone plates can withstand cyclic bending stresses encountered in clinical use.
