  1. 21. Experimental investigation of rolling losses and optimal camber angle

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Bethuel Karanja; Elin Skoog; [2015]
    Keywords : ;

    Abstract : This Bachelor thesis project is an experimental investigation of the effect of camber and toe angles on rolling resistance. The experiments are done on Sleipner, a Prototype car made by KTH students, which takes part in the Shell Eco Marathon competition in Rotterdam. READ MORE

  3. 22. Rolling resistance during cornering - Impact of lateral forces for heavy-duty vehicles

    University essay from KTH/Optimeringslära och systemteori

    Author : Helena Olofson; [2015]
    Keywords : Bicycle model; lateral forces; rolling resistance; velocity optimization; Cykelmodell; sidokrafter; rullmotstånd; hastighetsoptimering; bränsleförbrukning;

    Abstract : We consider first the single-track bicycle model and state relations between the tires’ lateral forces and the turning radius. From the tire model, a relation between the lateral forces and slip angles is obtained. The extra rolling resistance forces from cornering are by linear approximation obtained as a function of the slip angles. READ MORE

  4. 23. Däckutrustningens påverkan på miljö och driftsekonomi vid rundvirkestransport

    University essay from SLU/Dept. of Forest Products

    Author : Gustaf Röhfors; [2015]
    Keywords : däck; singelhjul; CTI; ekonomi; logistik; transportkostnader; tires; single tires; economy; logistics; transportation costs;

    Abstract : Lastbilstransporter av rundvirke har och kommer att vara ett viktigt led i svensk skogsindustri. På grund av ökade priser på drivmedel har kostnaderna för transport av virke stigit kraftigt den senaste tioårsperioden. READ MORE

  5. 24. Investigation of the transient nature of rolling resistance on an operating Heavy Duty Vehicle

    University essay from Umeå universitet/Institutionen för fysik

    Author : Petter Lundberg; [2014]

    Abstract : An operating vehicle requires energy to oppose the subjected driving resistances. This energy is supplied via the fuel combustion in the engine. READ MORE

  6. 25. Expanding the brush tire model for energy studies

    University essay from KTH/Fordonsdynamik

    Author : Francesco Conte; [2014]
    Keywords : Multi-Line Brush Tire model; Masing model; rolling resistance;

    Abstract : Considering the more and more important issues concerning the climate changes and the global warming, the automotive industry is paying more and more attention to vehicle concepts with full electric or partly electric propulsion systems. The introduction of electric power sources allow the designers to implement more advanced motion control systems in vehicle, such as active suspensions. READ MORE
