It uses beams to conduct stress tests and other types of mechanical testing. These beams rotate several times and attach shafts at opposing ends with . A large-scale fatigue testing machine based on the rotating beam method in a four-point bending configuration was designed and built. With the device, high-strength metal specimens with a 32-mm gauge diameter and a 100-mm gauge length can be tested at a cyclic frequency of up to 48 Hz. In this work, particular attention was paid to evaluating the spatial .
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.
The machine performance was evaluated using test specimens which were machined in conformity with standard procedures. It was observed that the machine has the potentials of generating reliable bending stress – number of cycles data; and the cost of design (171,000 Naira) was lower in comparison to that of rotating bending machines from abroad.A fast rotating bending fatigue test machine Figure 1 - R.R.
