Dynamic simulation study of friction and lubrication on ICE bearings

Friction and lubrication analysis of internal combustion engine bearings is studied. A series of software implementary precepts for mathematical modeling, to analytic calculating and realizing simulation outcome are brought forward. As a dynamic simulating technique is introduced into the process of engine bearing design, simulation models of the oil film are built and the emulational analysis of the shaft center track is carried out. A software program package "Engine Bearing Friction and Lubrication Dynamic Simulation System" is developed to realize the real-time simulation of the working status of bearing during the design process. Through developing virtualized products, the defects of the improved product design can be found in time and the products can be at once. Thus the purpose of predicting and controlling the cost, quality and design period of the products can be achieved.
