  1. 1. Suspension design for off-road construction machines

    Författare :Adam Rehnberg; Lars Drugge; Annika Stensson Trigell; David Crolla; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; construction machine; engineering vehicle; earth mover; wheel loader; vehicle dynamics; vehicle engineering; whole body vibrations; off-road vehicle; anläggningsmaskin; entreprenadmaskin; hjullastare; fordonsdynamik; fordonsteknik; helkroppsvibrationer; terrängfordon; Vehicle engineering; Farkostteknik;

    Sammanfattning : Construction machines, also referred to as engineering vehicles or earth movers, are used in a variety of tasks related to infrastructure development and material handling. While modern construction machines represent a high level of sophistication in several areas, their suspension systems are generally rudimentary or even nonexistent. LÄS MER

  3. 2. Improving a six-wheeler’sperformance both on- and off-road

    Författare :Olof Noréus; Annika Stensson Trigell; Johan Widberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle engineering; Farkostteknik;

    Sammanfattning : In vehicles with electric transmission and independent wheel stations, there is apossibility to control propulsion, steering and suspension individually for eachwheel. This makes it possible to improve mobility in terrain as well as performanceand driving safety on road. LÄS MER

  4. 3. Modelling driver behaviour in run-off-road crashes: Applications in safety system development and safety benefit estimation

    Författare :Daniel Nilsson; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; advanced driver assistance systems; effectiveness assessment; run-off-road crashes; predictive processing; driver behaviour; cluster analysis;

    Sammanfattning : Run-off-road crashes have been identified as a major concern for automobile safety and several advanced driver assistance systems (ADASs) targeting run-off-road crashes are on the market today. Assessment of ADASs require relevant test scenarios and valid computational models of driver behaviour. LÄS MER

  5. 4. Optimisation of Off-Road Transport Missions

    Författare :Jörgen Albrektsson; Jan Åslund; Lars Eriksson; Nikolce Murgovski; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Mines, construction sites, road construction and quarries are examples of applications where construction equipment are used. In a production chain consisting of several construction machines working together, the work needs to be optimised and coordinated to achieve an environmental friendly, energy efficient and productive production.

  7. 5. Safety for Children in Cars – Focus on Three Point Seatbelts in Emergency Events

    Författare :Isabelle Stockman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steering; Crash test dummies; Run-off road; Child restraint systems; Child safety; Emergency events; Braking; Pre-pretensioners;

    Sammanfattning : Child safety in vehicles has improved over time. One of the main factors is due to the increased restraint use by children. Nevertheless, studies show that although children are restrained, injuries still occur indicating that restraint systems have the potential for further improvement. LÄS MER
