By Michele Schirru

This thesis offers a unique ultrasonic device for non-invasive and in-situ characterization of magazine bearing lubricant viscosity. specifically, the applying to magazine bearings is defined by means of non-invasively measuring the viscosity and localized strength losses all through operation. 
This ultrasonic viscometer relies at the mirrored image of polarized shear waves from a skinny resonating coating layer to extend the dimension sensitivity, compared to traditional ultrasonic tools. This device permits an entire engine oil viscoelastic characterization in-situ. 
The publication investigates the results of temperature, strain and shear fee, and describes intimately the ultrasonic setup and strategy. additional, it demonstrates that an identical process should be utilized equally to watch the lubrication of alternative engine parts. As such, it bargains a distinct device which could force the study of oil formulations to enhance engine functionality and satisfy the necessities of overseas gas economic climate regulations.
