متن کاملFundamentals of Fluid Film Journal Bearing Operation and Modeling
Widely used in turbomachinery, the fluid film journal bearing is critical to a machine’s overall reliability level. Their design complexity and application severity continue to increase making it challenging for the plant machinery engineer to evaluate their reliability. This tutorial provides practical knowledge on their basic operation and what physical effects should be included in modeling ...
متن کاملThermo-elasto-hydrodynamic (TEHD) analysis of oil film lubrication in big end bearing of a diesel engine
Nowadays, due to the increasing power of diesel engines, especially heavy duty diesel engines, and increasing gas pressure inside the combustion chamber, the forces acting on the engine bearings have dramatically raised. On the other hand, becaus eof the competition in the market, it is necessary to increase the engine bearing life and reduce its failure as much as possible. The engine bearings...
متن کاملA New Profile Measurement Method for Thin Film Surface
In order to measure the surface profile of the thin films in wide area with high accuracy, the research on the new measurement method was conducted and many patents on measurement method and system were researched. Based on the physical properties of soft thin film, the method of using white interferometer and ball cantilevers for measuring the surface profile of thin film is proposed. Then, th...
