MDT uses Instron ElectroPuls® E1000 Test Instruments for both static and dynamic (high frequency) applications. These testers are ideal for applications requiring a combination of dynamic or complex motions, high frequency, enhanced fidelity, and high cycle count. They are capable of loads as high as 1000N and have been used in applications requiring extraordinarily high cycle counts. Various test fixture designs for the E1000 can accommodate up to 16 samples, depending on the fixture. The instruments also include versatile T-slot tables for regular and irregular grips and specimens. The instrument can be operated in either displacement or load control. For multi-specimen applications, transducers for monitoring each specimen can be added to provide individual data collection.
Typical test applications for the ElectroPuls® E1000 include:
The ElectroPuls® E3000-LT (Linear Torsion) instruments retain the high frequency/high cycle capabilities of the ElectroPuls® E1000 while providing higher force capability. Four of these six systems at MDT include a patented biaxial actuator that is capable of applying simultaneous axial and torsional loads. The E3000 can be used in a variety of static and dynamic applications requiring either higher forces for mechanical failure or a higher driving force for complex fixtures. The instruments also include versatile T-slot tables for regular and irregular grips and specimens. Common medical device testing applications include large stent graft bend tests and other peripheral devices, hip implants, dental implants, and other orthopaedic devices. The instrument can be operated in either displacement or load control. For multi-specimen applications, transducers for monitoring each specimen can be added to provide individual data collection.
Test applications for the ElectroPuls® E3000-LT include:
|Model||Max Load||Max Frequency||Max Stroke|
|ElectroPuls® E1000||+/-1000N (225lb)||200Hz||+/- 30mm (1.18in)|
|ElectroPuls® E3000||+/-3000N (675lb)||200Hz||+/- 30mm (1.18in)|
Environmental controls and chambers:
Most tests require a controlled temperature and/or saline environment. MDT Services has chambers for testing in both air and saline at temperatures to 37°C utilizing various baths, enclosures, special fixturing and heating/circulation systems.
