Visual Computation of Thermohydrodynamic Lubrication of Dynamically Loaded Journal Bearings

The Reynolds equation and energy equation with the thermal balance equation in combination were applied to build the thermohydrodynamic (THD) computational model of the dynamically loaded journal bearings. The most popular development platform——Visual C ++ in the field of computer science and the drawing platform of AutoCAD were combined with the medium of ObjectARX and the object oriented programming technology was used, on the basis of which, the visual computational software of the THD lubrication of the dynamically loaded journal bearings for main shaft and connecting rod bearings of automobile engines was developed. The analysis results of an example indicate that the bearing behaviors are closely tied to the radial clearances and inlet lubricant temperature of the bearing.
