Fatigue Testers come in a variety of sizes and shapes including
mini, micro, portable, bench table models, benchtop, desktop and
tabletop versions. They may be used, second hand, home made, diy.
There are also multistation, multiaxial, and multichannel configurations.
Fatigue Test Equipment are engineered to satisfy multiple demands
from customers, including design specifications, dynamic force requirements,
electric systems, flexible reconditioned and simple needs. The applications
are wide and many types, including need for reconditioned upgrade
used utm type machines, as well as simple small structural testers.
Sunder is in here somewhere. Fatigue Test Equipment are available
in different packages depending on maker, prices, sale cost, and
whether it is best or not. The purchase depends on the supplier
companies and comparison of different advantages. It also depends
whether they are available in a catalog or not. Fatigue Test Equipment
are designed based on servo hydraulic and electro dynamic power
packs and match mechanical force or load and speed specifications
or requirements. The load frames feature high alignment and screw
driven crosshead adjustment mechanisms. The axial force capacity
is matched to high speed or high frequency speed requirements and
cyclic performance or cycle counts. Data is collected in the form
of stress strain curves. Load elongation or extension plots can
be output and yield or ultimate strength determined. The analysis
may include endurance, ductility, and fatigue limits. Control software.
Fatigue Test Equipment , when outfitted with the correct tensile
fatigue grips, compression fatigue platens, or flexural reverse
bending fatigue fixtures, can test a wide variety of test samples,
specimens, and coupons. Bolts, button head samples, dogbones, cable,
fiber (or fibre), pipe, plate, wire rope, thin metal foil or sheet,
spring and threaded samples all can be tested. Also round samples
such as tube, tubing, pipe, welds and wire may be tested. Fatigue
Test Equipment perform a wide variety of tests including fatigue
fracture strength, fatigue loading, fatigue tensile and compression,
thermomechanical fatigue, or TMF, low cycle fatigue, or LCF, and
high cycle fatigue, or HCF. Three (3) point bend flexural or flexion
tests as well as four (4) point bend flexing tests are common. Tensil
strength tesing including pull pull tests are even possible. Planar
biaxial shear tests are uncommon. Lap shear tension low cicle fatigue
also. Pressure load spectrum random fatigue tests are rare but possible.
Material types that are commonly tested on Fatigue Test Equipment
include aluminum (or aluminium), advanced or aerospace composites,
elastomers or rubber, polymers or plastics, metals including nitinol,
rebar, steel and copper. Honeycomb sandwichs and interlaminar fatigue
and fracture research is common. ------------------ |
