  1. 1. Advancing the life cycle energy optimisation methodology

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Hamza Bouchouireb; Ciarán J. O'Reilly; Peter Göransson; Rupert J. Baumgartner; José Potting; Tracy Bhamra; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; life cycle energy; vehicle design; optimisation; functional conflicts; livscykelenergi; fordonsdesign; optimering; tvär-funktionella konflikter; Farkostteknik; Vehicle and Maritime Engineering;

    Abstract : The Life Cycle Energy Optimisation (LCEO) methodology aims at finding a design solution that uses a minimum amount of cumulative energy demand over the different phases of the vehicle's life cycle, while complying with a set of functional constraints. This effectively balances trade-offs, and therewith avoids sub-optimal shifting between the energy demand for the cradle-to-production of materials, operation of the vehicle, and end-of-life phases.

  2. 2. Robust design Accounting for uncertainties in engineering

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : David Lönn; Larsgunnar Nilsson; Niclas Strömberg; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robust optimisation; robust design; robustness; meta model; sensitivity analysis; TECHNOLOGY Engineering mechanics Solid mechanics; TEKNIKVETENSKAP Teknisk mekanik Fastkroppsmekanik;

    Abstract : This thesis concerns optimization of structures considering various uncertainties. The overall objective is to find methods to create solutions that are optimal both in the sense of handling the typical load case and minimising the variability of the response, i.e. robust optimal designs.

  3. 3. Quasi-analytical Modelling and Optimisation Techniques for Transport Aircraft Design

    University dissertation from Institutionen för flygteknik

    Author : Askin T. Isikveren; [2002]
    Keywords : aircraft; conceptual; design; specifications; atmosphere; geometry; weight; aerodyanmics; propulsion; operational performance; stability and control; constrained multi-objective optimisation; computer aided design; regional; business; high-transonic; ;

    Abstract : The research work presented here focuses on the subject oftransport aircraft design at the pre-design or conceptuallevel. The primary topics addressed are: (1) generation of avast array of new quasi-analytical expressions to permit aconceptual treatment of commercial and business transportaircraft with adequate sensitivity for more advanced tradestudies; (2) review and adoption of a method to predictstability and control characteristics (using the Mitchellmethod); (3) a study of the relative merits between variousmethods in facilitating an expedient and robust constrainedmulti-objective optimisation result within the context oftraditional conceptual design problems (Genetic Algorithms andNelder-Mead Simplex search); (4) creation of a software packageas a new and unique conceptual tool that permits the generationof design proposals in an accurate yet expeditious manner; and,(5) practical demonstration of the new conceptual designsoftware package by undertaking some actual aircraft designproposals.
