  1. 16. Managing R&D Processes - Focusing on Technology Development, Product Development, and their Interplay

    Författare :Dennis Nobelius; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; organizational interfaces; integration; project scope; product development; research and development; management issues; technology development;

    Sammanfattning : This thesis concerns management of research and development (R&D) processes, with an emphasis on technology development and product development and their interplay. The aim is to assist companies in leveraging their R&D efforts and to improve the understanding of R&D management. LÄS MER

  3. 17. Analysis of the Base Wake on Passenger Vehicles

    Författare :Lennert Sterken; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pressure measurements; External aerodynamics; Wind tunnel; Wake; Local drag; CFD;

    Sammanfattning : Car manufacturers are presented by a continuous increase in fuel prices and by ever more strict legislations regarding CO2-emissions. Decreasing the driving resistance and hence the fuel consumption of their vehicles helps to improvetheir market share. LÄS MER

  4. 18. Becoming a keystone: How incumbents can leverage technological change to create ecosystems

    Författare :Gouthanan Pushpananthan; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Innovation ecosystem; discontinuous technological change; modularity; case study;

    Sammanfattning : The proliferation of digital technology and automation in the 21st century has created a need to revisit established theories on value creation. Exponential advances in Internet of Things (IoT) technologies are dismantling firm- and industry-specific value creation processes. LÄS MER

  5. 19. Aerodynamics of two trucks driving in close-proximity

    Författare :Johannes Törnell; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drag; aerodynamics; cab over engine; inter-vehicle distance; lateral offset; side wind; truck; platooning; yaw; close proximity; wake;

    Sammanfattning : There are several factors driving the development of vehicles with higher efficiency in society, chief among them are the emissions of greenhouse gases and their contribution to global warming. Therefore, there is a strong incentive to improve heavy-duty trucks' energy efficiency, supported by new legislation. LÄS MER

  7. 20. Numerical and Experimental Investigations on Aerodynamic and Thermal Aspects of Rotating Wheels

    Författare :Alexey Vdovin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ventilation resistance; wind tunnel; brake cooling; ride height; aerodynamic moment; CFD; rim design; vehicle aerodynamics;

    Sammanfattning : With todays and future environmental legislations for CO2 and other emission gases, all vehicle manufacturers are forced to further develop tools and methods to make their vehicles more energy efficient and environmentally friendly. One option to achieve this is to reduce the aerodynamic resistance since it has a significant influence on the vehicle fuel consumption, especially for velocities higher than 50 km/h. LÄS MER
