Radial shaft seals are frequently used in power transmission systems to prevent oil leakage. The importance of these components for operational reliability provides a great challenge for the industry. Pertinent design and standardisation of key surface parameters such as surface texture and machine lead angle or shaft lead are paramount. The former is an inherent property of any surface, which is also commonly referred to as surface roughness whilst the latter is formed during manufacture of the shafts.The often contradictory objectives of efficiency, effective sealing and reliability require a combined numerical and experimental approach. A numerical model accounting for surface interactions and hydrodynamic flow in the mixed regime of lubrication will be created. The numerical model will be used to understand the underlying physics and inform design. In parallel, a component level test rig will be created to experimentally validate the numerical model and to benchmark new components designs. Additionally, new standards will be created to characterise the waviness and roughness of the contact surfaces measured using optical interferometers.

径向轴密封件经常用于动力传输系统中以防止漏油。这些组件对于运行可靠性的重要性为行业带来了巨大的挑战。关键表面参数（例如表面纹理和机器导程角或轴导程）的针对性设计和标准化至关重要。前者是任何表面的固有属性，通常也称为表面粗糙度，而后者是在轴的制造过程中形成的。效率、有效密封和可靠性这三个经常相互矛盾的目标需要结合数值和实验方法。将创建一个数值模型，用于解释混合润滑状态下的表面相互作用和流体动力流动。数值模型将用于理解基础物理并为设计提供信息。与此同时，将创建一个组件级测试装置，以通过实验验证数值模型并为新组件设计进行基准测试。此外，还将创建新的标准来表征使用光学干涉仪测量的接触表面的波纹度和粗糙度。
