  2. 6. Synchronous Belt Mechanics and Durability - An Investigation Towards Life Prediction

    Author : Tomas Johannesson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; load distribution model; synchronous; camshaft drives; mathematical modelling; timing; belt; dynamic; wear; simulation; automotive; belt life prediction;

    Abstract : An automotive synchronous belt transmits power and assures accurate timing between the crankshaft and camshafts. The automotive industry is very competitive: there is constant pressure to increase performance and lower costs. READ MORE

  4. 7. Model-based Prognostics for Prediction of Remaining Useful Life

    Author : Madhav Mishra; Jyoti Kumar Sinha; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance Engineering;

    Abstract : Prognostics and healthmanagement (PHM) is an engineering discipline that aims to maintain the systembehaviour and function, and assure the mission success, safety andeffectiveness. Health management using a proper condition-based maintenance (CBM)deployment is a worldwide accepted technique and has grown very popular in manyindustries over the past decades. READ MORE

  5. 8. Acetabular Revisions. Risk Factors and Prediction of Re-revision

    Author : Maziar Mohaddes; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Osteoarthritis; Hip; Register studies; Radiostereometry; Acetabular revision; Trabecular metal;

    Abstract : Hip replacement is a successful intervention when treating patients with hip osteoarthritis. Approximately 10% of all patients undergoing primary hip replacement surgery require further surgical interventions (revisions) during their lifetime. Acetabular component (cup) failure is the most common reason for a revision. READ MORE

  6. 9. Sensitivity of Aeroelastic Properties of an Oscillating LPT Cascade

    Author : Nenad Glodic; Damian Vogt; Matthew Montgomery; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flutter; aeroelastic response; combined modes; bending-torsion flutter; mode superposition; aerodynamic asymmetries; ROM; probabilistic analysis;

    Abstract : Modern turbomachinery design is characterized by a tendency towards thinner, lighter and highly loaded blades, which in turn gives rise to increased sensitivity to flow induced vibration such as flutter. Flutter is a self-excited and self-sustained instability phenomenon that may lead to structural failure due to High Cycle Fatigue (HCF) or material overload. READ MORE

  7. 10. Contribution to Numerical and Experimental Studies of Flutter in Space Turbines. Aerodynamic Analysis of Subsonic or Supersonic Flows in Response to a Prescribed Vibratory Mode of the Structure

    Author : Hakim Ferria; Pascal Ferrand; Torsten Fransson; François Moyroud; France Ecole Centrale de Lyon Laboratoire de Mécanique des Fluides et d'Acoustique; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flutter; space turbine; LRANS computation; flutter measurement; shock wave boundary layer interaction; blisk; cut-on cut-off condition; interblade phase angle; combined modes;

    Abstract : Modern turbomachines are designed towards thinner, lighter and highly loaded blades. This gives rise to increased sensitivity to flow induced vibrations such as flutter, which leads to structure failure in a short period of time if not sufficiently damped. READ MORE
