  1. 1. Simplified Life Cycle Assessment Approaches and Potential Impact Shifts

    University dissertation from Stockholm : Kungliga Tekniska högskolan

    Author : Katja Tasala Gradin; KTH.; KTH.; [2020]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LCA simplification approach; impact shift; reduction measures; road transport; streamlining; screening; Machine Design; Maskinkonstruktion;

    Abstract : Road transport contributes to approximately one quarter of all EU greenhouse gas emissions and is the leading cause of air pollution in cities. There are significant measures aimed at the reduction of use phase environmental impacts; in the EU, these strategies focus on the decarbonisation of road transport, such as through the prioritization of low- and zero-emission vehicles.

  2. 2. On synchronization of heavy truck transmissions

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Daniel Häggström; KTH.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; synchronization; synchronizers; gear shift; gearbox; synkronisering; växling; växellåda; Machine Design; Maskinkonstruktion;

    Abstract : Gear shifts are becoming more and more important as engines are adapted to low speed high torque working conditions. Synchronizers are key components for successful gear shifts. To adapt the synchronizers to new working conditions due to adaptations to new engines, improved development tools are needed. READ MORE

  3. 3. Supporting complete vehicle reliability forecasts

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Julia Lindén; KTH.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reliability forecast; interactive function; operating conditions; Machine Design; Maskinkonstruktion;

    Abstract : Reliability is one of the properties that customers of heavy trucks value highest.Dependent on all parts and functions of the vehicle, reliability is a complexproperty, which can normally be measured only towards the end of a developmentproject. At earlier development stages, forecasts can give valuable decision supportfor project planning. READ MORE

  4. 4. A methodology for situated and effective design of haptic devices

    University dissertation from KTH Royal Institute of Technology

    Author : Xuan Sun; KTH.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design optimization; haptic devices; metamodel; multi-criteria; situatedness; Machine Design; Maskinkonstruktion;

    Abstract : The realism of virtual surgery through a surgical simulator depends largely on the precision and reliability of the haptic device. The quality of perception depends on the design of the haptic device, which presents a complex design task due to the multi-criteria and conflicting character of the functional and performance requirements.

  5. 5. Methodological Simplification in Comparative Life Cycle Assessment and Consequences on Validity

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Katja Tasala Gradin; KTH.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life Cycle Assessment; internal validity; external validity; comparative LCA; isolated part; omitted part; road vehicles; drivetrains; disc brakes; isolation criteria checklist; Machine Design; Maskinkonstruktion;

    Abstract : Life Cycle Assessment (LCA) is central to the development of sustainable products. LCA assesses the environmental impact of a product, service, or system through-out its whole life cycle, from material extraction to end-of-life phase. READ MORE
