Rotating Beam Fatigue Testing Machine

Based on wohler s design it uses a motor to rotate a circular cantilever specimen with a load at its free end.

Rotating beam fatigue testing machine.

The force giving rise to the bending moment do not rotate. Rotating fatigue machine this machine demonstrates the fatigue failure of materials when subject to alternating stresses. The purpose is to carry out rotating bar bending fatigue tests without deliberately introducing stress concentration in accordance with din 50113. Rotating beam fatigue testing systems were first developed in the mid 1800s by a german railroad engineer named august wöhler.

Fatigue dynamics offers a full service line of fatigue testing machines which include rotating beam fracture testing plate bending and crack initiation testing equipment. The advanced materials research laboratory amrl is home to three r r. The specimen functions as a simple beam symmetrically loaded at two points. The machine design is based on the rotating beam principle.

Additionally we can machine test samples and perform testing onsite per customer specifications with reporting. 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.
