Rotating Beam Fatigue Testing Machine

This paper presents the desi gn and fabrication of a new m echanical fatigue testing machine based on rotating beams with the o bjective of test ing high cycle fatigue and service life loads.

Rotating beam fatigue testing machine. He designed the machine to test railroad car axles and investigate axle brake failures. The machine design is based on the rotating beam principle. Moore rotary fatigue testing machines located in the mechanical testing laboratory. The principles upon which that machine was developed still apply today.

The specimen functions as a simple beam symmetrically loaded at two points. Rotating fatigue machine this machine demonstrates the fatigue failure of materials when subject to alternating stresses. Fatigue dynamics offers a full service line of fatigue testing machines which include rotating beam fracture testing plate bending and crack initiation testing equipment. Additionally we can machine test samples and perform testing onsite per customer specifications with reporting.

Rotating beam fatigue testing systems were first developed in the mid 1800s by a german railroad engineer named august wöhler. Rotary bending fatigue testing. The force giving rise to the bending moment do not rotate. A test piece mounted as a cantilever with single point loading is made to rotate and thus subjected to a bending moment.
