Preface

Before You Begin

Safety first! Before you attempt to use your MTS product or system, read and understand

the Safety manual and any other safety information provided with your system. Improper installation, operation, or maintenance of MTS equipment in your test facility can result in hazardous conditions that can cause severe personal injury or death and damage to your equipment and specimen. Again, read and understand the safety information provided with your system before you continue. It is very important that you remain aware of hazards that apply to your system.

Other MTS manuals In addition to this manual, you may receive additional MTS manuals in

paper or electronic form.

If you have purchased a test system, it may include an MTS System Documentation CD. This CD contains an electronic copy of the MTS manuals that pertain to your test system, including hydraulic and mechanical component manuals, assembly drawings and parts lists, and operation and preventive maintenance manuals. Controller and application software manuals are typically included on the software CD distribution disc(s).

What you need to

know

MTS Systems Corporation assumes that you know how to use your controller. See the appropriate manual for information about performing any controller-related step in this manual’s procedure. You are expected to know how to perform the following procedures:

• Turn hydraulic pressure on and off.

• Select a control mode.

• Manually adjust the actuator position.

• Install a specimen.

• Define a simple test.

• Run a test.

MTS Advantage Screw Action Grips Functional Description

The MTS Advantage Screw Action Grips are designed for static tension testing. The grips are supplied with socket head cap screws for servohydraulic load unit installations; optional pin adapters and other mounting accessories are available for electromechanical test systems.

MTS Advantage™ Screw Action Grips Introduction

The grips have serrated knobs that are used to manually apply an initial gripping force on the specimen. For grips rated above 100 N (25 lbf), once the specimen is hand tightened into the grips, a torque wrench is used to ensure there is adequate clamping. The torque wrench also compresses a compliant compression puck to ensure the face surfaces follow specimen deformation during elongation. The tensile load pulls the face surfaces, forcing them to pivot around a pin. The pivoting reduces the clamping pressure at the top of the face surfaces and increases it at the bottom of the face surfaces. Rotation of the face surfaces reduces the likelihood of a failure in the high stress area of the clamp.
