Thermo Mechanical Fatigue Test System
Bi-00-702 Thermo Mechanical Test Systems simulate
combined effects of thermal cycling and mechanical fatigue. These
systems are useful for testing specimens subjected to synchronized
heating, cooling and temperature compensated strain or force with
optional expansion to simultaneous torsion or internal pressurization.
These fully integrated test systems are available in the range of 50 to
500 kN force ratings and are ideally suited for aerospace and power
generation industries.
The specimen under test is subjected to
extreme temperatures followed by rapid cooling by means of a digitally
controlled induction heater and pneumatic air directed on the specimen
through air cooling nozzles.
Water cooled self locking and auto
aligning hydraulic grips, high temperature extensometer, temperature
sensors and load cell are typical components of the test system
controlled by a 2370 series controller with synchronized data
acquisition up to 5 kHz.
