Rotating Beam Fatigue Testing Machine

The force giving rise to the bending moment do not rotate.

Rotating beam fatigue testing machine.

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

The specimen functions as a simple beam symmetrically loaded at two points. The advanced materials research laboratory amrl is home to three r r. The purpose is to carry out rotating bar bending fatigue tests without deliberately introducing stress concentration in accordance with din 50113. The principles upon which that machine was developed still apply today.

The machine design is based on the rotating beam principle. A test piece mounted as a cantilever with single point loading is made to rotate and thus subjected to a bending moment. He designed the machine to test railroad car axles and investigate axle brake failures. Rotating beam fatigue testing systems were first developed in the mid 1800s by a german railroad engineer named august wöhler.
