Fatigue Testing Machine

This is a rotating beam type machine in which load is applied in reversed bending way. The standard 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 fibres of the specimen is produced during each revolution. The bending moment 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 a Digital counter. An interlocking system puts off the motor at specimen failure. The machine meets requirements of IS 5075-1969 and consisting of the followings- 

  • The test machine with the machine bed.
  • Electrical control panel with starter indication lamp, main switch, counter, multi-pin socket and four core wire
  • Weight hanger
  • Balancing weight
  • Set of weights comprising of 50gm – 8No.s, 100gm – 6No.s, 200gm – 10No.s, 500gm – 2No.s, 1Kg – 6Nos, 10kg – 1No & 20 kg- 1No.

Note – High capacity machine up to 400kgcm bending moment can also be supplied on request.
