MTS Planar Biaxial Test Systems Delivering a full spectrum of planar biaxial testing capabilities

MTS PLANAR BIAXIAL SERVOHYDRAULIC TEST SYSTEMS ARE DEPLOYED WORLDWIDE TO CHARACTERIZE STRUCTURES, COMPONENTS AND MATERIALS SUBJECTED TO COMPLEX MULTI-AXIS LOADS FOR INDUSTRIES SUCH AS AEROSPACE, CIVIL ENGINEERING, RAIL, GROUND VEHICLES, AND MORE.

Planar biaxial mechanical testing is critical for characterizing complex design structures, components, and orthotropic and anisotropic lightweighting materials. Finding equipment that enables test engineers to simulate real-world conditions, however, can be challenging. This equipment needs to stress the specimen in multiple directions while allowing test engineers to exert a great deal of control over the process. To meet these challenges, MTS offers a family of versatile servohydraulic test systems designed to deliver a full spectrum of static and dynamic planar biaxial testing capabilities...

A Comprehensive Portfolio of Planar Biaxial Load Frames The MTS planar biaxial system family features a complete array of ultra-stiff, standard servohydraulic load frames, dynamically rated to deliver loads ranging from 25 kN per actuator to 500 kN per actuator. The actuators are arranged orthogonally (X and Y axes) in a single plane and the frame stands vertically, so one sees the X and Y planes as a front view. The +/-50 mm stroke (100 mm total stroke) actuators used in the frame are specially designed for planar biaxial testing with low internal oil volume to increase system stiffness. Hydrostatic...

Superior System Alignment Capabilities MTS planar biaxial load frames exhibit superior system alignment, which minimizes bending strain to enhance test accuracy and reduce data scatter. Proper alignment prevents unintentional bending stress that can put the specimen at higher risk of buckling or early failure. Minimizing potential specimen damage is important in many industries where the specimen can be very expensive to replace. 5 MTS Planar Biaxial Systems have spherical bearing alignment mechanisms that are used to adjust the concentricity and the angularity of the specimen grips to maintain...

Increased Safety Through the Passive Restraint System Passive restraints are included on the systems to preclude actuator damage in the event of specimen failure that otherwise may force the actuator rod to bend. The restraints are sturdy structures integral to the reaction frame which surround the grip bodies. There are polymer pads positioned to clear the grip bodies (no contact) for normal operation by a fraction of a millimeter. In the event of a compressive specimen failure, the grips come into contact with the polymer pads and are restrained from any further out-of-plane movement, thereby...
