Fatigue Testing Machine
Description & Specification
Technical Specifications
DESCRIPTION:
Higher capacities for each system can be accommodated based on customer needs.
A fatigue test helps determine a material’s ability to withstand cyclic
fatigue loading conditions. By design, a material is selected to meet or
exceed service loads that are anticipated in fatigue testing
applications. Cyclic fatigue tests produce repeated loading and
unloading in tension, compression, bending, torsion or combinations of
these stresses. Fatigue tests are commonly loaded in tension – tension,
compression – compression and tension into compression and reverse.
This machine is used to test the fatigue strength of materials and to
draw S-N diagram by research institute, laboratories, material
manufacturers and various industries. This is rotating beam type machine
in which load is applied in reversed bending fashion. The standard 8 mm
dia specimen is held in special holders at its ends and located such
that it experiences a uniform bending moment. The specimen is rotated at
4200 rpm by a motor. A complete cycle of reversed stresses in all
fibers of the specimen is produced during each revolution.
FEATURES:
• Simple lever system for changing load.
• Calibration in Nm available on request.
• Light weight, Simple design, Compact Size.
