  3. 2. Aerodynamic Investigation of Truck-Trailer Combinations

    Författare :Helena Martini; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aerodynamics; vehicle combinations; trucks; drag reduction;

    Sammanfattning : In today’s society, increasing fuel prices and the constantly evolving emission legislation, forces the vehicle industry to develop new techniques for the propul- sion of vehicles, and optimization of existing technology. Trucks constitute a significant proportion of the transportation system, consequently it is of great importance to ensure as low an impact as possible on the environment. LÄS MER

  4. 3. Aiming at Moving Targets : Applying Cognitive Work Analysis to Work Domains in Transition

    Författare :Ida Löscher; Anders Arweström Jansson; Åsa Cajander; Camilla Fröjd; Stas Krupenia; Catherine Burns; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cognitive work analysis; work domain analysis; control task analysis; strategies analysis; abstraction hierarchy; contextual activity template; activity prioritization; systems design; heavy vehicle development; long haul trucks; intensive care; nursing; digitalization.; Computer Science with specialization in Human-Computer Interaction; Datavetenskap med inriktning mot människa-datorinteraktion;

    Sammanfattning : The design of IT systems for complex work environments is essential for workers to be able to operate more effectively and efficiently. To design a system that supports the workers' specific tasks we need to understand the work demands and the context in which the system operates. LÄS MER

  5. 4. Wheel Housing Aerodynamics of Heavy Trucks

    Författare :David Söderblom; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : For trucks in long-haul operation the aerodynamic drag constitutes more than half of the total driving resistance, and by optimising the aerodynamics of thevehicle it is possible to reduce the fuel consumption significantly. The drag of the underbody, including wheels, wheel housings and engine compartment, accounts for a large part of that aerodynamic drag, and very little aerodynamic optimisation has been carried out in this specific area on heavy trucks.

  7. 5. Towards an Improved Safety Benefit Assessment for Heavy Trucks - Introduction of a framework for the combination of different data sources

    Författare :Ron Schindler; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; safety benefit assessment; GIDAS; Bayesian modelling; CARE; crash data analysis;

    Sammanfattning : Although heavy goods vehicles (HGVs) were only involved in 4.4% out of more than 1 million crashes that occurred on European roads in 2017, their share in crashes with fatal outcome was almost three times larger (12%). LÄS MER
