Chauhan, S (2010) Revival of an Electro-Magnetic Resonance (EMR) Machine. BTech thesis.
The EMR (Electro Magnetic Resonance) Machine has been designed for high cycle fatigue testing of materials (mainly metals). The EMR machine frame comprises two masses separated by a stiff spring. The „spring‟ consists of the specimen being tested, its gripping attachments and load cell. The spring/mass system is supported and guided by leaf springs. Each mass is attached to four leaf springs; the upper mass is attached to its support springs through two long columns. The two sets of support springs are separated by four Acme screws which pull together or push apart the nodal points of the upper and lower mass springs are to apply a compressive or tensile mean load when rotated by a servo motor through worm gears. The nodal points of the upper and lower mass springs are rigidly held to a cruciform and the use of two contra – oscillating masses eliminates the need for a heavy and cumbersome seismic block. Here our work is to restore the Electro Magnetic Resonance machine, as due to some electrical circuit fault and further many breakages the machine stopped working at all. So in final year this project“Revival of the EMR machine ”is allotted as interdisciplinary project work for Mechanical Engineering and Electrical Engineering.
