چکیده
Abstract This contribution presents an elastohydrodynamic lubrication (EHL) model for pneumatic spool valves. For accurate estimation of the transient friction this tribological sealing system, surface topography cylindrical counterfaces valve housings are measured and analyzed with optical measurement instrument. Based on data, properties flow factors system derived. It has been found that consideration a significant influence simulation results EHL model, lowering calculated force by up to 20 %.

3D simulation considering surface condition of wall in particle method
We have experimentally observed the forms of splash caused by spheres diving into water, where the spheres are made of hydro-gel or acrylic resin[1]. The experimental results have shown that the splash by the hydro-gel sphere has formed the crown-type one, whereas the acrylic sphere formed the column-type one despite the same experimental condition. This means that the surface condition of wall...
متن کامل3D Surface Topography from Intensity Images
This paper demonstrates how a new shape from shading scheme can be used to extract topographic information from 2D intensity imagery. The shape-from-shading scheme has two novel ingredients. Firstly, it uses a geometric update procedure which allows the image irradiance equation to be satisfied as a hard-constraint. This not only improves the data-closeness of the recovered needle-map, but also...
متن کاملCharacterization of 3D surface topography in 5-axis milling
Within the context of 5-axis free-form machining, CAM software offers various ways of toolpath generation, depending on the geometry of the surface to be machined. Therefore, as the manufactured surface quality results from the choice of the machining strategy and machining parameters, the prediction of surface roughness in function of the machining conditions is an important issue in 5-axis ma...
متن کاملEngineering Critical Assessments of Marine Pipelines with 3D Surface Cracks Considering Weld Mismatch
Offshore pipelines are usually constructed by the use of girth welds, while welds may naturally contain flaws. Currently, fracture assessment procedures such as BS 7910 are based on the stress-based methods and their responses for situations with large plastic strain is suspicious. DNV-OS-F101 with limited modifications proposes a strain-based procedure for such plastic loads. In this paper 3D ...
متن کاملOn the nature of surface roughness with application to contact mechanics, sealing, rubber friction and adhesion.
Surface roughness has a huge impact on many important phenomena. The most important property of rough surfaces is the surface roughness power spectrum C(q). We present surface roughness power spectra of many surfaces of practical importance, obtained from the surface height profile measured using optical methods and the atomic force microscope. We show how the power spectrum determines the cont...
