  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. Vehicle dynamic analysis of wheel loaders with suspended axles

    Författare :Adam Rehnberg; Annika Stensson Trigell; Lars Drugge; Peter Eriksson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hjullastare; arbetsmaskin; fordonsdynamik; fordonsteknik; Vehicle engineering; Farkostteknik;

    Sammanfattning : The wheel loader is a type of engineering vehicle used primarily to move crude material over shorter distances. As the vehicle is designed without wheel suspension, wheel loader drivers are exposed to high levels of whole body vibration which influences ride comfort negatively. LÄS MER

  5. 4. Exploiting over-actuation to reduce tyre energy losses in vehicle manoeuvres

    Författare :Mohammad Mehdi Davari; Annika Stensson Trigell; Jenny Jerrelind; Patrick Gruber; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : Due to environmental and economic challenges road vehicles need bettersolutions to reduce energy consumption. Improvement in tyre rolling e-ciency is one of the key enablers for lower energy consumption. The shifttowards electrication and intelligent driving creates new opportunities todevelop energy-ecient vehicles. LÄS MER

  7. 5. Exploring force allocation control of over actuated vehicles

    Författare :Johannes Edrén; Annika Stensson Trigell; Jenny Jerrelind; Lars Drugge; Jonas Fredriksson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : As the concern for environmental changes and diminishing oil resources grows more and more, the trend of new vehicle concepts now includes full electric or partly electric propulsion systems. The introduction of electric power sources enables more advanced motion control systems due to electrification of the vehicle's actuators, such as individual wheel steering and in wheel hub motors.
