摘要：
A marine sliding bearing is selected as the research subject to investigate the effect of high-order element on the calculation of lubrication. On the basis of theories of hydrodynamic lubrication and high-order element, the lubrication region is meshed with unstructured grid technology, and the 2D Reynolds equation is solved by the non-structural grid finite volume method. Thus, the calculation model of sliding bearing's lubrication is established based on high-order element. Computation results of lubrication show that when the number of nodes is consistent, the amount of high-order element decreases, but the maximum pressure, the counterforce of oil film, the end leakage flow, and the friction coefficient are close to the reference value. When the high-order element is considered in the lubrication calculation, the calculation time is prolonged, but the precision is relatively increased. The theory of high-order element can be applied to the solution of lubrication characteristics of sliding bearings. Copyright ©2020 Journal of Harbin Engineering University.
