Standards
(1)YY/T 1429
(2)ISO 16402
These standards specify the testing procedures for evaluating the fatigue properties of polymethyl methacrylate (PMMA)-based bone cement. Rectangular specimens are tested under quasi-static or cyclic loading conditions using a four-point bending method to determine the flexural strength or fatigue life of the specimen.
The system provides professional testing fixtures (including water bath environments) and precise, effective standard operating procedures (SOPs) to support comprehensive mechanical performance analysis of bone cement.
Application
The Bone Cement Flexural Fatigue Testing Machine is used to evaluate the mechanical durability and flexural fatigue performance of bone cement under repeated bending loads. It simulates long-term stresses that bone cement experiences in orthopedic implants, ensuring safety and reliability. Typical applications include:
Orthopedic material testing: Assess fatigue life of bone cement used in joint replacements.
Quality control: Verify consistency and mechanical performance of manufactured bone cement batches.
Research and development: Support optimization of bone cement formulations and mechanical properties.
Standards compliance: Conduct tests according to ISO 5833. ASTM F2118. and other orthopedic material testing guidelines.
This machine ensures bone cement can withstand repeated physiological flexural loads, reducing the risk of implant loosening or failure.
Product Features
Next-generation fatigue testing system driven by a large electromagnetic motor as the actuation core.
Direct-drive electromagnetic motor ensures stable operation and high repeatability, providing precise force and displacement control.
Built-in electromagnetic actuator with low friction and high repeatability; system response is fast 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.
Various fixtures and accessories are available for different test setups.
