Rotating Fatigue Machine Apparatus

Product Description

Descriptions of DIDAC Rotating Fatigue Machine ApparatusThis Rotating Fatigue Machine Apparatus has been designed to introduce students to the effects of fatigue. A motor rotates a specimen through a gear and pulley arrangement which can be adjusted. During the rotation the specimen is subject to sinusoidal variation of bending stress. The loading system cancels its own self-weight enabling any desired value of bending stress to be applied. Loads are applied to the test specimen using a load hanger and a set of calibrated weights. When failure occurs, a micro switch stops the motor and the cycles to failure are registered on a revolution counter. A safety guard shields all rotating parts. The Rotating Fatigue Machine Apparatus is mounted on a heavy base plate and is designed to overhang the bench. Specially machined necked test specimens are provided.Experimental CapabilitiesRotating Fatigue Machine Apparatus To make an introductory study of fatigue using a Wohler rotating fatigue apparatus, including the time to failure caused by various stress levels and materials Introducing students to S-N curvesVarying materials on fatigue limits Specimen geometry Specifications Rotating Fatigue Machine ApparatusThis Rotating Fatigue Machine Apparatus has been designed to introduce students to the effects of fatigue.
