Pradeep K. Gupta Inc. (PKG Inc.) provides computer modeling of rolling bearings. The company's ADORE software is an advanced computer program for the real-time simulation of dynamic performance of rolling bearings. The classical differential equations of motion of each bearing element, including rolling elements, cage and races, are formulated in ADORE using a generalized six-degrees-of-freedom system, while the applied forces and moments are derived from intricate mathematical models for interacting bearing elements. A real-time integration of the equations of motion provides the basic foundation for the bearing performance simulation. In addition, the company specializes in areas such as: Rolling element bearing lubricant modeling; Elastohydrodynamic lubrication; High temperature materials and solid lubricants; Thermal interactions; Cage dynamics; Wear in rolling bearings; Contact mechanics; Coated solids; Stress distribution and coating optimization; Surface Topography; Asperity interactions; Rough surface modeling; Hydrodynamic bearings; Fluid film; Rotating machinery systems; Rotor response Critical speeds and design optimization.
