  2. 1. On valve controlled fluid power systems : flow amplifier and percussive rock drilling

    Author : Henrik Pettersson; Matti Vilenius; Linköpings universitet; []
    Keywords : ;

    Abstract : This thesis discusses how the design of hydraulic systems and components can be made to meet the demands of a future market in terms of efficiency, flexibility and cost. It also discusses how computer simulation can support the designer to get a higher knowledge of the system and to make the design phase more efficient. READ MORE

  4. 2. Noise radiation from drill steels : and other experimental investigations in acoustics and fluid mechanics

    Author : Jan-Erik Ögren; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Drill rod noise has become a major noise source in percussive drilling. Generation of flexural waves, which seem to be responsible for most of the noise, is studied in a model with dynamic photoelasticity and in the real drill rod with strain gauge technique. READ MORE

  5. 3. Machinability Testing of Materials in Metal Cutting with Focus on Compacted Graphite Iron and Cutting Fluids

    Author : Varun Nayyar; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UTS.; Boring; Drilling; Cutting Fluid; Turning; Milling; Force; Wear; Force; Torque; Compressed air; CGI; Hardness; Tool Life; Material Properties; Chip Microstructure; Tapping;

    Abstract : Due to the stringent demands for lower emission from trucks require better mechanical properties of the material to be used in the engines. Better efficiency necessitates higher peak pressure in the engines and for traditionally used material, Flake Graphite Iron (FGI), the mechanical properties starts to reach the limit of what the material can withstand.

  6. 4. Performance Testing of Cutting Fluids and Tool Holders in Metal Cutting

    Author : Varun Nayyar; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chip Microstructure; Torque; Drilling; Compressed air; Turning; Tool-holding; Force.; Tapping; Keyword: Cutting Fluid;

    Abstract : ABSTRACTThe metal cutting industry has evolved over the last century to the point where an increasing range and complexity of tool holding systems and cutting fluids are available for metal machining in the market. Most of the companies report their cutting fluid cost to be between 7 -17 % of the manufacturing cost. READ MORE

  7. 5. Parameters optimization of oil well drilling operation

    Author : Ali Darwesh; Thorkild Maack Rasmussen; Nadhir Al-Ansari; Daniel Ask; Bernt Sigve Aadnøy; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bazian Block; Kurdistan; Iraq; Optimization; Drilling Parameters; Rate of Penetration; Wiper trips; Kicks; Pay zone; Bourgoyne and Young model; Exploration Geophysics; Prospekteringsgeofysik;

    Abstract : In the beginning of 2005, the ministry of natural resources in the Kurdistan region of Iraq dividedits territory into more than 50 oil blocks based on geological setting. These oil blocks were awardedlater to different international oil companies for oil investments based on Production SharingContracts (PSCs). READ MORE
