Electro Fatigue Testing Machine

Model: EPS Series


EPS series Electro Fatigue testing machine are fast acting table-top testers ideally suitable for performing static and dynamic fatigue tests on a variety of materials and components. These electro-dynamic machines use a linear electric motor with an adjustable upper cross-head of a stiff dual column frame. The electro-dynamic actuator is connected to single phase power, which resulting in a clean low maintenance solution. With dynamic force capacities, the Electro Fatigue testing machines are used to evaluate the mechanical properties of biologic materials, composites, orthopedic fixation devices, prostheses, spinal constructs, stents, dental implants, elastomeric materials and others.

Software system
The Test & Motion DynPack module is the software for dynamic tests. DynPack offers the collection, processing and display of measurement data from up to ten channels at the same time. Whereas up to five channels are processed with a data acquisition rate of 5kHz.
DynPack displays the following information in parallel windows on the screen: measured values in a digital manner, on-line graph with reduction of data, the covering curve and the oscilloscope window. It is possible to assign simple limits as well as inner and outer limits to the amplitude for each working block. The assignment can be done in a relative absolute manner.
DynPack communicates with several EDCs simultaneously. Hence, a two or three-axis-system can be controlled easily. A function generator with sine, square, ramp, triangle and sinusoidal functions is included. Furthermore, it is possible to sweep between frequencies and amplitudes and to superimpose different curve forms.
