高水平的摩擦限制了润滑微机电系统（MEMS）器件的可靠性。本文探讨了在MEMS中采用滑移结合纹理表面以提高性能特性的可能性。基于极限剪应力模型，建立了修正的雷诺方程。据证实，相比于未纹理化的表面以及单独纹理化的表面，采用滑移的纹理化表面具有低得多的摩擦系数，这不受纹理单元纵横比的影响。结果表明，组合纹理/滑移图案通过增加负载能力和降低摩擦而具有有益效果。
High level of friction limits the reliability of lubricated micro-electro-mechanical-systems (MEMS) devices. The current paper explores the possibility of employing slippage combined with a textured surface in MEMS in order to improve performance characteristics. A modified Reynolds equation based on the limiting shear stress model is developed. It is confirmed that compared to an untextured surface as well as a solely textured surface, the textured surface employing a slippage has a much lower coefficient of friction, which is not affected by the texture cell aspect ratio. The results indicate that the combined textured/slippage pattern has a beneficial effect by increasing the load capacity and decreasing the friction.
