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. The machine design is based on the rotating beam principle. The specimen functions as a simple beam symmetrically loaded at two points. Moore rotary fatigue testing machines located in the mechanical testing laboratory.

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. Oem manufacturer of fatigue testing machine dynamic fatigue testing for springs computerised rotating bending fatigue testing machine fatigue testing machine for bridge bearing pads offered by tec sol india original manufacturer software for advanced material testing machines calibration chennai tamil nadu. 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. But we can perform fatigue tests for various shapes of specimens if we use the rotating bending fatigue testing machine here explained.

When using high strength materials it is very important to consider not only the fatigue strength but also the presence of surface defects when determining the fatigue life of components. This test reproduces a load condition to which the wheel is subject to when in use. 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. In particular during this test the main stresses are developed in the central part.

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. Specialized torsion system for rotating beam 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. 2 when we use the ultrasonic fatigue instrument the shape of a specimen is restricted depending on the resonance conditions.

During determination of bending fatigue strength the specimen is subjected exclusively to alternating loading in order to obtain a mean value of zero.
