  1. 11. Assessing design strategies for improved life cycle environmental performance of vehicles

    Författare :Sofia Poulikidou; Anna Björklund; Per Wennhage; Gregory Keoleian; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle design; Design strategies; Lightweight design; Electric vehicles; Design for Environment DfE ; DfE tools; Life cycle assessment LCA ; Simplified LCA; Composite materials; Planering och beslutsanalys; Planning and Decision Analysis;

    Sammanfattning : Vehicle manufactures have adopted different strategies for improving the environmental performance of their fleet including lightweight design and alternative drivetrains such as EVs. Both strategies reduce energy during use but may result in a relative increase of the impact during other stages. LÄS MER

  3. 12. Integration of Design for Environment in the vehicle manufacturing industry in Sweden : Focus on practices and tools

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design for Environment DfE ; ecodesign; vehicle design; DfE tools; ecodesign tools; product development; integrated product development;

    Sammanfattning : Design for Environment (DfE) promotes the systematic consideration of environmental aspects during product design and development. Despite the maturity of concepts and tools in literature, efficient implementation in industries is reported to be low. LÄS MER

  4. 13. Light-weighting Methodology in Rail Vehicle Design through Introduction of Load Carrying Sandwich Panels

    Författare :David Wennberg; Sebastian Stichel; Per Wennhage; Ragnar Larsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sandwich panels; rail vehicle; lightweight; optimisation; carbody; Vehicle engineering; Farkostteknik; Construction engineering; Konstruktionsteknik; Construction materials; Konstruktionsmaterial;

    Sammanfattning : Lightweight design in rail vehicles has been important for quite some time. Structures have been optimised to fulfill their purpose and cut unnecessary weight to reach allowable axle loads. Classically this is done by using steel, thin-walled structures, throughout the car body, or, alternatively, power-pressed aluminum profiles. LÄS MER
