Fatigue Testing Machine
This machine is used to test the fatigue strength of material and to draw S-N diagram by research institute, laboratories, material manufacturers and various industries. This is a rotating beam type machine in which load is applied in reserved 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 movement. The specimen is rotated at 4200 rpm by a motor. A complete cycle of reversed stresses n all fibers of the specimen is produced during each revaluation.
The bending movement is applied with a lever system and can be easily changed by moving a weight over the lever. Total number of revolutions at which the specimen fails are recorded by digital counter. An interlocking system puts off the motor at specimen failure. Machine meets requirements of IS 5075 – 1969
