Rotating Bending Fatigue Testing Machine

The rotating bending test is a fatigue test that allows to evaluate the resistance of the wheel exploiting a rotating bending moment obtained through a rotating unbalanced mass.

Rotating bending fatigue testing machine.

In particular during this test the main stresses are developed in the central part. This test reproduces a load condition to which the wheel is subject to when in use. The iabg rotating bending test machine allows the time and cost saving determination of the fatigue strength of high strength materials such as those used in. During determination of bending fatigue strength the specimen is subjected exclusively to alternating loading in order to obtain a mean value of zero.

But we can perform fatigue tests for various shapes of specimens if we use the rotating bending fatigue testing machine here explained. Specialized torsion system for rotating beam testing. Rotating beam fatigue testers are one of the oldest methods used to determine a material s fatigue behavior. Rotary bending fatigue testing.

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. The purpose of the rotating bar bending fatigue test as per din 50113 1982 and iso 1143 2010 is to determine the bending fatigue strength properties of round specimens under rotating load. 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. 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.

The advanced materials research laboratory amrl is home to three r r. The machine design is based on the rotating beam principle. Moore rotary fatigue testing machines located in the mechanical testing laboratory. The specimen functions as a simple beam symmetrically loaded at two points.

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.
