Development of an Ultrasonic Sensing Technique to Measure by Michele Schirru

By Michele Schirru

This thesis provides a unique ultrasonic device for non-invasive and in-situ characterization of magazine bearing lubricant viscosity. particularly, the appliance to magazine bearings is defined by way of non-invasively measuring the viscosity and localized energy losses all through operation. 
This ultrasonic viscometer is predicated at the mirrored image of polarized shear waves from a skinny resonating coating layer to extend the size sensitivity, compared to traditional ultrasonic tools. This software allows a whole engine oil viscoelastic characterization in-situ. 
The publication investigates the results of temperature, strain and shear cost, and describes intimately the ultrasonic setup and strategy. extra, it demonstrates that an identical strategy should be utilized equally to watch the lubrication of different engine elements. As such, it deals a special software that may force the examine of oil formulations to enhance engine functionality and satisfy the necessities of overseas gasoline economic system regulations.
