Abstract In the case of parallel surfaces, such as the oil control ring, no load carrying capacity is generated without texture. A flow conserving multigrid code is used to solve the hydrodynamic lubrication equation described by the Reynolds equation. This code is used to investigate the influence of texture geometry (dimples) and its position along the contact. In particular the behavior of the load carrying capacity according to the texture position on the central line of the contact is studied. To generate positive load carrying capacity, only partial texturing must be used. A significant difference can be observed between inlet texturing and outlet texturing. A multigrid code has been developped that allows a comparison between Dirichlet and periodic results. A comparison with equivalent step bearings is made to analyse the load carrying capacity.

凹坑对平行面承载能力的影响

摘要 在平行表面的情况下，如控油环，没有纹理就不会产生承载能力。流动守恒多重网格代码用于求解由雷诺方程描述的流体动力润滑方程。此代码用于研究纹理几何形状（凹坑）及其沿接触位置的影响。特别是根据接触中心线上的纹理位置研究了承载能力的行为。为了产生正承载能力，必须仅使用部分纹理。在入口纹理和出口纹理之间可以观察到显着差异。已经开发了一个多重网格代码，可以比较狄利克雷和周期性结果。
