Rotating Beam Fatigue Testing Machine

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

Rotating beam fatigue testing machine.

Rotating beam fatigue testing systems were first developed in the mid 1800s by a german railroad engineer named august wöhler. Moore rotary fatigue testing machines located in the mechanical testing laboratory. The purpose is to carry out rotating bar bending fatigue tests without deliberately introducing stress concentration in accordance with din 50113. Additionally we can machine test samples and perform testing onsite per customer specifications with reporting.

The machine design is based on the rotating beam principle. The principles upon which that machine was developed still apply today. He designed the machine to test railroad car axles and investigate axle brake failures. Rotating fatigue machine this machine demonstrates the fatigue failure of materials when subject to alternating stresses.

The specimen functions as a simple beam symmetrically loaded at two points. Based on wohler s design it uses a motor to rotate a circular cantilever specimen with a load at its free end. A test piece mounted as a cantilever with single point loading is made to rotate and thus subjected to a bending moment. Rotary bending fatigue testing.
