Rotating Fatigue Machine Apparatus

Product Description

Descriptions of DIDAC Rotating Fatigue Machine Apparatus

This 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 Capabilities Rotating Fatigue Machine Apparatus

1. 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
2. Introducing students to S-N curvesVarying materials on fatigue limits
3. Specimen geometry
