  1. 31. 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]
    Keywords : Rolling resistance; Air drag; Heavy Duty Vehicles; Vehicle dynamics; Complete vehicle test; Coastdown; Effective radius; ACEA; Pneumatic tires; Driving resistances; Energy efficiency; Rullmotstånd; Luftmotstånd; Tunga fordon; Fordonsdynamik; Helfordonstest; Utrullningstest; Effektiv radie; ACEA; Pneumatiska däck; Körmotstånd; Energieffektivitet.;

    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

  3. 32. Parametrizing tyre wear using a brush tyre model

    University essay from KTH/Aerodynamik; KTH/Fordonsdynamik

    Author : Henry Salminen; [2014]
    Keywords : ;

    Abstract : Studying rubber wear is important because it can save money, minimize health and environmental issues related to the particles generated from tyre wear and reduce fuel consumption. The wear of rubber is considered to be the result of energy dissipation due to friction. READ MORE

  4. 33. Non-isotropic Cosmology in 1+3-formalism

    University essay from Linköpings universitet/Matematiska institutionen; Linköpings universitet/Tekniska högskolan

    Author : Johan Jönsson; [2014]
    Keywords : Non-isotropic cosmology; Einstein; Relativity; Bianchi Type I; 1 3-covariant formalism;

    Abstract : Cosmology is an attempt to mathematically describe the behaviour of the universe, the most commonly used models are the Friedmann-Lemaître-Robertson-Walker solutions. These models seem to be accurate for an old universe, which is homogeneous with low anisotropy. READ MORE

  5. 34. A Survey of Dynamical Billiards

    University essay from KTH/Matematik (Inst.)

    Author : Markus Himmelstrand; Victor Wilén; [2013]
    Keywords : ;

    Abstract : In this report we will present the basic concepts and results of the theory of dynamical billiards which idealizes the concept of a volumeless ball re　ecting against the inside of a billiard table without friction.This motion will continue indenitely and it is of interest to study its behaviour.

  6. 35. Model calibration of a wooden building block

    University essay from Institutionen för bygg- och energiteknik (BE)

    Author : Ali Abdul Jabbar Karim; Johan Lessner; Mehrdad Moridnejad; [2013]
    Keywords : Wood; Dynamical behaviour; Finite element model; light weight assembly; Experimental modal analysis; Wooden;

    Abstract : Constructing multi floor buildings by light weight material have increased recently. There are many advantages of using light weight material, such as wood, for the environment. However, one of the deficiencies of lightweight material is the acoustic performance. READ MORE
