Bending Fatigue Testing Machine

The standard 8 mm dia specimen is held in special holders at its ends and located such.

Bending fatigue testing machine.

Rotating beam fatigue testers are one of the oldest methods used to determine a material s fatigue behavior. This machine is used to test the fatigue strength of materials and to draw s n diagram by research institute laboratories material manufacturers and various industries. This is rotating beam type machine in which load is applied in reversed bending fashion. Specialized torsion system for rotating beam testing.

To perform a test with admet s rotating beam tester a sample is placed in the machine and a force is applied via a bending moment using weights hung off the sample. These machines test the bending fatigue limit of metals under the action of symmetrical repeatedly. Tests which can rotate up to 18 000 rpm generating cyclic s tresses at 300 hz. To provide full scale testing of the fatigue performance of our products apollo designed built and commissioned the world s first large scale rotating bending fatigue tester.

Nicknamed the rotatamatron 3000 the machine is capable of applying a constant stress across a 2 75 in 70 mm diameter reduced section with a maximum load of 50 000 lbs. Rotatory bending machine the purpose of the rotating bar bending fatigue test is to determine the bending fatigue strength properties under rotating load.
