  1. 41. Sustainable performance of wet clutch systems

    Författare :Kim Berglund; Rikard Mäki; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Sammanfattning : In industry today there are increasing demands not only on product performance, but also on environmental performance. In striving to develop high performance environmentally adapted products, optimization of product life is a central issue. LÄS MER

  3. 42. Reliable Assessments of Concrete Structures with Corroded Reinforcement: An Engineering Approach

    Författare :Mattias Blomfors; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anchorage; safety formats.; reliability; reinforced concrete structures; bond; finite element modelling;

    Sammanfattning : When in service, concrete structures are inevitably exposed to detrimental processes which, over time, can affect the structures’ ability to fulfil their structural requirements. The most common cause of deterioration of concrete structures is corrosion of the reinforcement; a problem that is expected to become more severe in future, due to climate change. LÄS MER

  4. 43. Structural Analysis of Existing RC Bridge Deck Slabs Structural Analysis of Existing RC Bridge Deck Slabs

    Författare :Jiangpeng Shu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; load-carrying capacity; assessment; Reinforced concrete RC bridge deck slabs; structural behaviour; Finite element FE analyses;

    Sammanfattning : Due to ageing of the bridge stock, continuously increasing load requirements, the need for assessing existing bridges is becoming increasingly important. Reinforced concrete (RC) bridge deck slabs are among the most critical parts to the load carrying capacity of bridges. LÄS MER

  5. 44. Online State Estimation in Electrified Vehicles Linked to Vehicle Dynamics

    Författare :Anton Albinsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric vehicles; state estimation; vehicle dynamics; parameter estimation; tyre-road friction estimation; active safety;

    Sammanfattning : Electric vehicles have the potential to significantly reduce energy consumption and emissions for personal and commercial road transport and number of electric vehicles is likely to increase in the future due to stricter emission legislations. In order to accelerate market penetration, the competiveness of electric vehicles should increase in comparison to conventional vehicles. LÄS MER

  7. 45. Driver behavior models for evaluating automotive active safety: From neural dynamics to vehicle dynamics

    Författare :Gustav M Markkula; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; simulation; active safety; control behavior; system evaluation; Driver models;

    Sammanfattning : The main topic of this thesis is how to realistically model driver behavior in computer simulations of safety critical traffic events, an increasingly important tool for evaluating automotive active safety systems. By means of a comprehensive literature review, it was found that current driver models are generally poorly validated on relevant near-crash behavior data. LÄS MER
