  • surface asperity flattening in sheet metal forming a 3 d relocation stylus profilometric study
    International Journal of Machine Tools & Manufacture, 1995
    Co-Authors: X Roizard, J Von Stebut
    Abstract:

    Abstract Among the laser textured steel sheets retained for difficult stamping situations those with isolated, non communicating valleys are shown to be especially interesting. Such isolated valleys act simultaneously as traps for wear debris and as practically frictionless, High Pressure Oil pockets, participating in overall load carrying. These results are substantiated by 3D profilometry before and after friction to analyse specific residual roughness and friction-induced surface damage on the load carrying plateaux.

  • Research on sealing performance and self-acting valve reliability in High-Pressure Oil-free hydrogen compressors for hydrogen refueling stations
    International Journal of Hydrogen Energy, 2010
    Co-Authors: Xin Dianbo, Feng Jianmei, Peng Xueyuan
    Abstract:

    Abstract Piston ring sealing and valve design play an important role in High-Pressure Oil-free reciprocating compressors for hydrogen refueling stations. The severe non-uniformity of the Pressure distribution was suggested to be the root cause of the premature failure of the sealing rings, and therefore a mathematical model was established to simulate the unsteady flow within the gaps of piston rings, based on which the Pressure distribution was obtained and the mechanism of the non-uniform abrasion of the rings was disclosed. The method to equalize the Pressure difference through each ring was proposed by re-distributing the cut size of each ring, and it was validated experimentally. Aiming at the problem that the self-acting valves in hydrogen compressors could be easily destroyed by severe impact, this paper investigated the motion and impact of valves theoretically and experimentally, based on which the methodology was explored to design the parameters of valves for hydrogen compressors.
