The Femoral Stem Fatigue Testing Machine is a device used to evaluate the fatigue performance and durability of artificial femoral stems under repeated mechanical loading.
(1)YY/T 0809.4
(2)ISO 7206-4
These standards specify the test methods and performance requirements for fatigue testing of stemmed femoral components in partial and total hip replacements under defined conditions. Fatigue tests are conducted at a frequency of 1–30 Hz, load ratio R = 0.1. maximum load 2300 N, for 5 million cycles or until specimen failure.
Next-generation fatigue testing system using large electromagnetic motor as the actuation core.
Direct-drive electromagnetic motor ensures stable operation and high repeatability for precise force and displacement control.
Built-in electromagnetic actuator with low friction and high repeatability, providing fast system response and high speed.
Capable of performing tension, compression, bending, shear, creep, and relaxation tests.
Meets modern material testing requirements for high precision, high frequency, stability, and durability.
Features oil-free, seal-free, maintenance-free operation, long service life, high integration, easy installation, and compact footprint.
Offers a variety of fixtures and accessories for different test setups.
