  1. 1. Development architecture for industrial data management

    Author : Yujiang Li; Lars Mattsson; Sivard Gunilla; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Information modeling; ISO 10303 STEP; CAx; API; SRA - Produktion; SRA - Production;

    Abstract : Standardized information modeling is important for interoperability of CAx systems. Existing information standards such as ISO 10303 STEP have been proposed and developed for decades for this purpose. READ MORE

  2. 2. Towards Design Automation for Additive Manufacturing : A Multidisciplinary Optimization approach

    Author : Anton Wiberg; Johan Andersson (Ölvander); Johan Persson; Lars Pejryd; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In recent decades, the development of computer-controlled manufacturing by adding materiallayer by layer, called Additive Manufacturing (AM), has developed at a rapid pace. The technologyadds possibilities to the manufacturing of geometries that are not possible, or at leastnot economically feasible, to manufacture by more conventional manufacturing methods. READ MORE

  3. 3. Numerical Investigation of the Aerodynamic Vibration Excitation of High-Pressure Turbine Rotors

    Author : Markus Jöcker; KTH; []
    Keywords : Aeroelasticity; Aerodynamics; Stator-Rotor Interaction; Excitation Mechanism; Unsteady Flow Computation; Forced Response; High Cycle Fatigue; Turbomachinery; Gas-Turbine; High-Pressure Turbine; Turbopump; CFD; Design;

    Abstract : The design parameters axial gap and stator count of highpressure turbine stages are evaluated numerically towards theirinfluence on the unsteady aerodynamic excitation of rotorblades. Of particular interest is if and how unsteadyaerodynamic considerations in the design could reduce the riskofhigh cycle fatigue (HCF) failures of the turbine rotor. READ MORE
