Load Frame TestingMedical Device Testing
Load frame testing is a critical part of product design, development, and manufacture. Well designed test protocols yield the information required to determine the strength of a chosen material, and the reliability of a particular design. Through the application of a cyclic load to an object, we are able to gain an understanding of how the object will perform in actual use. The load application may be repeated millions of times at a frequency of several times per second for fatigue testing.
What equipment do you use for testing?
We perform all of our load frame testing using the Electropuls™ E10000 Linear-Torsion test frame, which is manufactured by Instron: a world leader in the material testing industry. Designed for both static and dynamic testing, it is capable of performing to more than 100Hz with a ±10kN dynamic linear load capacity, and a ±100Nm dynamic torque capacity.
What are the equipment specifications?
|Linear Dynamic Capacity||±10kN (2250lb)|
|Linear Static Capacity||±7.1kN (1600lb)|
|Torsion Capacity||±100Nm (880in-lb)|
|Linear Stroke||60mm (2.36in)|
Why is this type of testing important?
Load frame testing involves subjecting a test sample to various loading conditions to evaluate how it will perform over time. The real world effects of loading and fatigue show up as damage in the plastic and metal components of orthopaedic implants.Results of such tests allow manufacturers to make improvements needed to meet performance specifications and to create safer, stronger, more successful parts and products.
Can tests be performed under physiological conditions?
Tests can be performed in a protein-rich environment to mimic the corrosive media found in the body. For reproducing joint kinematics, please see our hip and knee simulator wear testing service pages.
