1. Tire and force distribution modeling and validation for wheel loader applications.
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : This thesis describes the development of a machine force distribution estimator and the calibration of tire models for wheel loader applications. Forces generated in the contact patch between the tires and the ground are crucial for understanding and controlling machine dynamics. LÄS MER
2. Rolling resistance during cornering - Impact of lateral forces for heavy-duty vehicles
Master-uppsats, KTH/Optimeringslära och systemteoriSammanfattning : 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. LÄS MER
3. Däckutrustningens påverkan på miljö och driftsekonomi vid rundvirkestransport
Master-uppsats, SLU/Dept. of Forest ProductsSammanfattning : 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. LÄS MER
4. Instability issues of an agriculturaltire testing convoy
Master-uppsats, KTH/FordonsdynamikSammanfattning : Michelin develops and manufactures tires. To check their tire, different tires tests are used. During the testing process of agricultural tires, some endurance tests are performed on a circular test track where a convoy, made of a truck pulling two single-axle trailers without suspension system, is driven at a constant speed.

5. Nedbrytning av vägar: Jämförelse mellan axlar med singel- respektive tvillingmontage
Uppsats för yrkesexamina på avancerad nivå, KTH/TransportvetenskapSammanfattning : When designing roads it’s important to know what loads will be driven on it. The axles on heavy vehicles can either have super single tires or dual tires which, according to studies, damage the roads differently. LÄS MER
