Testing frequencies, which equal up to 100 Hz, depending on the test, ensure short test times, yielding high specimen throughput.
testXpert III testing software is intuitive and workflow-based.
The LTM electrodynamic testing machines are used to determine the durability of materials and components in the finite life fatigue and high cycle fatigue ranges.
The LTM’s wide speed range allows it to be used for both dynamic fatigue tests and quasi-static tests. The oil-free drive, combined with ease of installation, makes the electrodynamic testing machine ideal for use in biomedical engineering and electronics, as well as for research and training. Typical examples include tests on hip-joint and knee replacements and dental implants. Other applications are tests on standard plastics and composites specimens, as well as aluminum and plastics CT and SEB specimens. The electrodynamic testing machine is available with loads of 1, 2, 3, 5 and 10 kN.

Description
The LTM is an electrodynamic testing machine with a drive based on linear motor technology. ZwickRoell's newly developed patented drive concept enables the LTM to be used for both dynamic and static materials and components testing. The low moved mass of the drive provides ideal conditions for performing fatigue tests with tensile, compression, and flexural loading.
The LTM is used in industries where oil-free and low-noise drive technology are preferred, for example, in the medical industry for standard-compliant testing of hip joint, knee, or dental implants.
Other typical application examples include fatigue and durability tests on standard specimens made of plastics, fiber composites and metals.
For components testing, the LTM is equipped with a T-slotted plate that can be adapted to components, and test fixtures quickly and easily as standard.
Intuitive operation via testXpert R and testXpert III software makes the LTM a genuine all-rounder for industrial purposes as well as for research and teaching at university level.
