  1. 21. Analysis of a gas turbine driven hybrid drive system for heavy vehicles

    Författare :Anders Malmquist; KTH; []
    Nyckelord :;

    Sammanfattning : The goal of this thesis has been to analyze the performanceand behavior of a gas turbine driven hybrid drive train. Thethesis covers both computer simulations and experimental tests.In two case studies, a number of measurements have been made ongas turbine driven hybrid vehicles that are developed by Volvoand ABB.

  3. 22. Towards Sustainability-driven Innovation through Product Service Systems

    Författare :Anthony Thompson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sustainable product innovation; sustainable product development; strategic sustainable development; product-service systems PSS ; decision support tools; life cycle management;

    Sammanfattning : Increasing awareness of anthropogenic impacts on the planet has lead to efforts to reduce negative environmental impacts in product development for several decades. Benefits to companies who focus on sustainability initiatives have been put forth more recently, leading to many efforts to incorporate sustainability considerations in their product innovation processes.

  4. 23. Planning Robotic Assembly Sequences

    Författare :Domenico Spensieri; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; robot routing and scheduling; path planning; Assembly planning; geometrical variation; cycle time optimization;

    Sammanfattning : In the automotive industry, short ramp up times and high product quality drive the development toward state-of-the-art solutions both in the research and industrial perspective. In addition to that, a sustainable industry requires optimized equipment utilization, in terms of materials used and consumed energy. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  7. 25. On maintenance optimization for offshore wind farms

    Författare :Francois Besnard; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; life cycle cost; optimization; maintenance; maintenance planning; Offshore wind energy; maintenance strategy; maintenance support organization; reliability;

    Sammanfattning : The maintenance cost is known to be an important part of the levelized cost of energy generated by wind parks. Operational costs can be significantly reduced by optimizing decisions for maintenance strategies, maintenance support organization and maintenance planning. LÄS MER
