Content

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.

Product Features

Next-generation fatigue testing system driven by a large electromagnetic motor.

Direct-drive electromagnetic motor ensures stable operation, high repeatability, and precise control of force and displacement.

Built-in electromagnetic actuator with low friction and high repeatability; high system responsiveness and speed.

Capable of performing tensile, compressive, bending, shear, creep, and relaxation tests.

Meets modern material testing requirements for high precision, high frequency, stability, durability, and reliability.

Oil-free, seal-free, maintenance-free, long life, highly integrated, easy installation, and compact footprint.

Wide selection of clamps and accessories available.
