Fatigue Testing Machine
Application And Operation :
This machine is used to test the Fatigue strength of materials and to draw S-N Diagram by research institutes, Laboratories, material manufacturers and various industries. This is a 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 loaded 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. The bending moment is applied with a lever system and can be easily changed by moving weight over the lever. Total number of revolutions at which the specimen fails is recorded by a Digital Counter. An interlocking system puts off the motor at specimen failure, Machine meets requirements of IS 5075-1959.
- Light weight, compact size, Simple design
- Table model, no need at foundation.
- Auto torque selector to adjust torque to specimen through gear box
- Simple lover System of changing bending moment load.
- Accurately Calibrated as per IS 5075.
(Machine with maximum bending moment up to 40Nm can be offered on request)
