摘要
基于EXCITE Power Unit软件,采用弹性流体动力润滑(EHD)的方法建立了某船用低速柴油机曲柄销轴承的仿真模型,使用有限元法和有限差分法对曲柄销轴承润滑性能进行了仿真,研究额定工况下曲柄销轴承油膜压力、油膜厚度、轴承比压、摩擦功耗等性能参数随曲轴转角的变化情况,为曲柄销轴承的设计选型提供理论依据。
Based on the soflware EXCITE Power Unit, the elastic-hydro-dynamic （EHD） model of the crankpin bearing of a low-speed marine diesel engine was built. The finite element method and finite difference method were used to simulate the lubrication perfomance of crankpin bearing, and to study performance parameters： oil film pressure, oil film thickness, bearing specific pressure and frictional power consumption of crankpin bearing at different crank angles at the rated condition to provide a theoretical basis for design and selection of crankpin bearing.
