SwRI Information

From relatively simple orbital analyses to more complex surface and subsurface stress analyses, Southwest Research Institute (SwRI)  bearing and tribological simulation capabilities help to quantify the sensitivity of the bearing to design parameters so the bearing geometry can be optimized.

	Orbital motion, main bearing 5

Optimizing the bearing geometry allows the engine design and analysis engineer to predict crankshaft dynamic behavior and to analyze bearing performance for:

• Bearing forces

• Minimum film thickness

• Oil film pressure

• Journal orbits

• Oil film friction/power loss

• Oil leakage flow rates

• Oil film temperature rise

• Film wet region and cavitation areas

Peak film pressure and minimum film thickness, main bearing 5
