Axial

The axial/torsional configuration of the
Bionix tabletop system enables biaxial
testing, controlling torsional moments up
to ±250 N·m (±2200 lbf·in) and totalrotations of 270°. It is excellent for testing
the durability and wear properties ofcomponents such as knee, hip and spine
implants. When paired with specialized
subsystems and accessories, it is capableof performing both simple and complex
kinematics studies of skeletal tissue andorthopaedic constructs.

The axial configuration of the Bionix
tabletop test system can be used toperform accurate and repeatable fatigue
life and fracture growth studies, as well as
tension, bending and compression testsof biomaterials. It runs tests up
to ±25 kN (5.5 kip) with standard
displacements of ±50 mm (± 2 in.), andcan easily be configured for monotonic or
fatigue testing.

Engineered for Performance
Advanced features ensure efficiency, safety and convenience

Bionix tabletop test systems deliver the high-performance features and functions that
researchers and device manufacturers need to ensure accurate results as well as
efficient, safe operation.

Highly stiff load frames

Exceptional safety

Highly efficient workspace

Bionix tabletop systems integrate Model
370.02 load frames. Combining stiffand precision-machined columns in acylinder-centric design, these load frames
provide superior rigidity, tight alignment
and exceptional ease of maintenance.
Fatigue-rated MTS actuators incorporated
directly into the cross-beam ensure
unsurpassed reliability for years of
accurate testing.

Bionix tabletop systems deliver a level ofsafety that exceeds the guidelines of CE andother organizations. Powered crosshead
positioning provides tight control oflifting and lowering for precise and easy
test space configuration. These systems also
restrict the actuator’s speed as it moves
into test position, preventing unexpectedmotion that could cause damage to thespecimen, the test system or the operator.
In addition, MTS grips provide positive
specimen gripping ensuring specimens
are attached securely and will not slip
during tests.

To ensure workspace accessibility andconvenience, Bionix tabletop test systems
incorporate a load frame stand with an
integrated T-slot table and channels tocontain spilled fluids. A compact systemhandset clearly displays test status, andprecision controls allow fine actuator
positioning.

Piloted end caps

Precision-machined connections between
the actuator cylinder and end-caps
guarantee precise, consistent alignment
over the life of the system, improving thereliability of the actuator and eliminating
the need for realignment after periodic
maintenance.
Innovative ergonomics

Bionix tabletop systems provide auser-friendly testing environment thatemphasizes operational safety andsimplifies test setup. This ergonomic
approach enables operators to perform
more tests safely and reliably with fewer
damaged or misaligned specimens.
On-frame controls keep operators focusedon the test space during setup. Conveniently
located to eliminate awkward bending
and reaching, these controls also featureeasy-to-turn handles and intuitive labeling.

4Integrated Solutions
Configurable for a wide range of biomedical applications

MTS offers the components and accessories biomedical researchers and manufacturers
need to conduct biomedical testing accurately and efficiently in accordance withworldwide standards.

Hydraulic power units

Controls

Load cells

MTS SilentFlo™ hydraulic power units(HPUs) power Bionix tabletop test systems
with superior flexibility and cost-efficiency.
They are engineered to handle continuousduty servohydraulic applications, andperform reliably, year after year. With
their quiet, clean and compact design,
MTS SilentFlo HPUs can be placed
directly on the test lab floor, eliminating
the expenses associated with managing aseparate pump room and transporting
hydraulic fluid across the test facility.

Versatile MTS FlexTest® digital controllers
deliver the flexibility to address a wide
range of biomedical testing applications.
They provide the high-speed closed-loop
control, data acquisition, function
generation and transducer conditioning
required for reliable multi-channel,
multi-station testing. FlexTest controllers
also offer superior scalability, so you
can use a single controller to manage
multiple load frames in the lab.

Additional load cells for Bionix tabletop
test systems are available with force
ratings down to 5 N (1 lbf). Load cellswith a lower force rating can typically beattached directly to the standard load cell.

Powerful software

MTS TestSuite™ Multipurpose Testing
Software provides a flexible and productive
environment for testing biomaterials andbiomedical components. Within thisenvironment, you can efficiently create,
run, report and conduct analysis acrossthe test lab. Available applications, modules
and options are designed to adapt toyour lab’s evolving needs, giving test
professionals the power to boost both
efficiency and productivity. You can easily
test to industry standards – or pursue yourown interpretation of a standard – using
customizable, plug-and-play modules.
The software also captures setup data andtest results, so you can quickly repeat tests.
