MTS Insight™ Material Testing System 14
Description
Introduction
Description
Every MTS Insight material testing system is comprised of a load frame,
electronic frame controller, and TestWorks software. The following figure shows
the external features of the various MTS Insight load frames.
The personal computer is also an integral part of the system. It runs TestWorks
software which provides full machine control, data acquisition and management,
and advanced data analysis and presentation. MTS has minimized the amount of
custom electronics required for your system, thereby making it flexible and
reliable. This is done by connecting the frame and the computer via standard
USB 2.0 connectors.
The load frame has a rectangular shape and includes a base unit and one or two
vertical columns. The two column models have a fixed upper transverse member.
The moving crosshead is driven by precision ball screws on the load frame. The
crosshead is coupled to the ball screw(s) with high-strength, precision ball nuts
and rides on the ball bearings. This configuration is very efficient in minimizing
friction and wear. The ball screws are anti-backlash. This feature removes the
backlash so that position can be measured with increased accuracy over
nonpreloaded ball screws.
The screws are driven by a series of pulleys and belts which in turn are driven by
a precision DC servo motor on the MTS Insight 1 through MTS Insight 50
models and an AC brushless motor on the higher force models. The ball screw is
connected to an optical encoder for precise position and velocity control.
