Stress analysis of main bearings under actual working conditions

Stress Analysis of Flight Vehicles under Flight Conditions

A method is presented for the stress analysis of flight vehicles under different flight conditions including gust and control surface deflection (or maneuver) using the governing equations of rigid-body motions and elastic deformations. The Lagrangian approach is used to derive the governing equations of motions. For this purpose, the basic equations of motions are derived in terms of potential...

Performance of Photovoltaics Under Actual Operating Conditions

A mixed-TEHD analysis and experiment of journal bearings under severe operating conditions

The increasingly high demands for compact design require journal bearings to work under severe operating conditions. A steadystate mixed-TEHD (thermo-elasto-hydrodynamic) model for journal bearings has been developed. The model considers the fluid flow in the gap formed by rough surfaces, asperity contact, surface thermoelastic deformations, and a temperature–pressure–viscosity relationship for...

Fingerprinting analysis of Oenococcus oeni strains under stress conditions.

Oenococcus oeni strains from traditional Italian red wines of the Basilicata region were investigated on the basis of their physiological and molecular response to different temperatures and ethanol concentrations. All strains were highly resistant to different ethanol concentrations and it has been observed that 7% ethanol was able to stimulate the growth of strains in wine, and 12-13% of etha...
