Bending Fatigue Testing Machine

Rotating beam fatigue testers are one of the oldest methods used to determine a material s fatigue behavior.

Bending fatigue testing machine.

This is rotating beam type machine in which load is applied in reversed bending fashion. 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. 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. Specialized torsion system for rotating beam testing.

The standard 8 mm dia specimen is held in special holders at its ends and located such. Rotatory bending machine the purpose of the rotating bar bending fatigue test is to determine the bending fatigue strength properties under rotating load. 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. 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.

This paper presents the design and development of a fast rotating bending test machine f or high cycle fatigue. Tests which can rotate up to 18 000 rpm generating cyclic s tresses at 300 hz.
