and Hydraulic Components from MTS
Servoactuator performance can dramatically impact
the repeatability of your testing and the validity of your test data.
That is why test engineers worldwide rely on MTS actuators and hydraulic
components to address their most demanding material, structural fatigue
and component testing requirements. These highly reliable,
energy-efficient offerings cover everything from high-dynamic time
histories to pseudo-static creep of highly brittle materials.
The MTS offering combines high-performance, fatigue-rated actuators with precision-engineered servovalves to ensure that the loads and displacements you direct toward the test article are precisely those applied at every moment in time. We also offer Active Load Abort technology to protect lab personnel and test articles in event of a mechanical malfunction, along with a range of accessories to help you further meet the needs of your application.
The family of MTS actuators ranges from Series
244 actuators for precise control of high-frequency motions and forces,
to the economical Series 201 actuator for static or low-frequency
testing, to heavy-duty rotary actuators that deliver reliable torque
generation. All MTS hydraulic actuators feature fatigue-rated
designs, which means they are built to exceed their rated loads for
millions of cycles. You can expect highly reliable performance over a
long functional life, helping to maximize your uptime and minimize total
cost of ownership.
MTS actuators are also engineered for precision. They deliver exceptional fidelity over the full range of motion, along with a superior ability to react to and counteract multiaxial forces. Proprietary materials and processes minimize friction for excellent reliability, wear-resistance and energy-efficiency.
LOAD ABORT COMPONENTS
Damage to an aerospace structural test article
can cost a test lab millions of dollars and thousands of lab hours. The
stakes are simply too high not to have proactive measures in place to
manage a power outage or mechanical malfunction during a test. The
MTS Active Load Abort (ALA) System effectively protects test articles
and lab personnel from the excessive — and often uncontrolled — energy
present in a test rig when an unexpected event arises. The MTS ALA
System provides complete control over planned loading and unintended
unloading of multichannel structural test systems. Combining advanced
FlexTest® controls, AeroPro™ software and a unique hydraulic manifold
design, the system reduces all actuator loads to a neutral state at
precisely the same time, regardless of varying pressures and positions
of individual actuators.
MTS also offers more economical passive (conventional mechanical) load abort technology to effectively unload hydraulic pressure in a variety of other structural testing applications. These constant-velocity manifolds protect test articles by incorporating an adjustable orifice that controls the flow rate of hydraulic fluid from each actuator.
Precision-engineered MTS servovalves deliver the
high-flow, quick-response and low-distortion performance required to
give you absolute control over your hydraulic actuation, helping you
uphold the highest levels of test data fidelity possible. Whether you
are controlling the position, load or velocity of hydraulic actuators or
require careful pressure control, MTS servovalves deliver exceptional
resolution and low hysteresis for exacting flow control.
Available in a wide range of flow ratings, these high-quality servovalves feature rugged designs to ensure long operating life, even in demanding test environments. Internal filtration protects nozzle orifices from contamination, and high spool driving forces reduce the risk of sticking due to dirty fluid.
Confidently meet the demands of closed-loop
servohydraulic testing with MTS swivels. These fatigue-rated swivels are
precision-engineered to deliver the strength, durability and versatility
required for optimal performance in a variety of structural testing
applications. MTS Series 249 and 249N swivels integrate seamlessly
with our actuator assemblies, seismic systems and simulation tables.
Available in a range of force ratings and sizes and either with or
without backlash adjustment, MTS swivels offer high axial stiffness for
exceptional high-frequency testing.
Most important, MTS swivels are optimized to deliver flawless performance and high reliability over years of heavy use. Fatigue-resistant ductile iron minimizes weight and maximizes strength. Maintenance-free, non-metallic bearings reduce friction, eliminate the need for lubrication and increase lifespan.
