摘要

This paper establishes thermal elastohydro-dynamics (TEHD) calculation model of crankshaft main bearing of internal combustion engine based on average Reynolds equation and dynamic adaptation equation considering asperity contact, analyzes its lubrication and friction characteristics, discusses mechanism of heat generation and heat exchange, and acquires corresponding effect law. Results show: most main bearings are in status of mixture lubrication, and generate heat through asperity contact and viscous friction; heat dissipation proportion of lubricating oil is 24.4%, and temperature rises 23.5°; as explosion pressure increases, power consumption is larger, oil temperature lowers, and minimum oil film thickness is reduced; while when oil supply pressure changes, the law of function is opposite.
