Rotating Beam Fatigue Testing Machine

Rotating fatigue machine this machine demonstrates the fatigue failure of materials when subject to alternating stresses.

Rotating beam fatigue testing machine.

The advanced materials research laboratory amrl is home to three r r. Additionally we can machine test samples and perform testing onsite per customer specifications with reporting. The principles upon which that machine was developed still apply today. Rotary bending fatigue testing.

The force giving rise to the bending moment do not rotate. The machine design is based on the rotating beam principle. Based on wohler s design it uses a motor to rotate a circular cantilever specimen with a load at its free end. The specimen functions as a simple beam symmetrically loaded at two points.

Rotating beam fatigue testing systems were first developed in the mid 1800s by a german railroad engineer named august wöhler. 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. He designed the machine to test railroad car axles and investigate axle brake failures. Fatigue dynamics offers a full service line of fatigue testing machines which include rotating beam fracture testing plate bending and crack initiation testing equipment.
