SV800 Rotating Fatigue Machine
The SV800 rotating fatigue machine has been designed to introduce students to the effects of material fatigue using a sinusoidal variation of bending stress
Description
The SV800 rotating fatigue machine has been designed to introduce students to the effects of material fatigue using a sinusoidal variation of bending stress.
A 2800rpm motor rotates a specimen through a gear and pulley arrangement between 5600 or 1400 rpm. The specimens are held within ‘keyless’ chucks and loaded using a cantilever arrangement, with the load being applied through a screw jack mechanism with integral cantilever load cell.
A digital interface displays the applied force and revolution count of the specimen. Both values can be reset and zeroed (tared) prior to the testing commencing. When specimen failure occurs, a micro switch stops the motor and the cycles to failure are registered on the digital display. The count remains when the motor is not running. A safety guard shields all rotating parts.
The supplied AIU Armfield interface unit allows a host computer (not supplied) to be connected to the SV800. The software supplied allows the capture and reviewing of data.
