  1. 1. Konstruktionsmaterial som återbrukar hela uttjänta bildäck : Material som används i jordskepp

    L3-uppsats, Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

    Författare :Soad Chahuan; Frida Nyberg; [2023]
    Nyckelord :;

    Sammanfattning : Idén om att använda däck som byggnadsmaterial uppmärksammades i en Tv-dokumentär. En miljöaktivist byggde ett hus och använde bildäck och annat som tar lång tid att degradera i marken som byggnadsmaterial. Det fångade intresset eftersom det är ett relevant sätt att återvinna "skräp" utan att påverka den globala uppvärmningen. LÄS MER

  3. 2. Creating a Virtual Tyre Temperature Sensor

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Oskar Zetterberg; Axel Tevell; [2023]
    Nyckelord :Tyre temperature; Virtual sensor; Soft sensor; Time series; Recurrent neural networks; LSTM; GRU; Mathematics and Statistics;

    Sammanfattning : To accurately determine the efficiency and range of an electric vehicle, one must be able to estimate the rolling resistance of the car. This is currently done using standardized methods developed under laboratory settings, where transient aspects and effects of varying temperatures are excluded. LÄS MER

  4. 3. Tyre Performance Estimation during Normal Driving

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Marcus Grip; [2021]
    Nyckelord :tyre performance; tread wear; tyre wear; online estimation; friction performance; velocity performance; friction potential; longitudinal stiffness; tyre stiffness;

    Sammanfattning : Driving with tyres not appropriate for the actual conditions can not only lead to accidents related to the tyres, but also cause detrimental effects on the environment via emission of rubber particles if the driving conditions are causing an unexpectedly high amount of tread wear. Estimating tyre performance in an online setting is therefore of interest, and the feasibility to estimate friction performance, velocity performance, and tread wear utilizing available information from the automotive grade sensors is investigated in this thesis.

  5. 4. Active and semi-active suspensions for articulated vehicles to minimise tyre wear

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :Haoran Zhang; [2021]
    Nyckelord :Articulated vehicle; tyre wear; quarter car model; semi-active and active suspension; Ledat fordon; däckslitage; kvartsbilsmodell; semiaktiv och aktiv fjädring;

    Sammanfattning : Tyre wear is a vital problem in vehicles, especially in articulated vehicles because of their heavier axle loads. Tyre wear can not only do harm to vehicle dynamics but also cause tyre particle emissions. Therefore, solutions that can minimise tyre wear are where this thesis work focuses. LÄS MER

  7. 5. Tyre sound classification with machine learning

    Uppsats för yrkesexamina på grundnivå, Högskolan i Gävle/Datavetenskap

    Författare :Aghyad Jabali; Husein Abdelkadir Mohammedbrhan; [2021]
    Nyckelord :Sound Classification; Machine learning; Support vector machine SVM ; Convolutional Neural Network CNN ; Random Forest.;

    Sammanfattning : Having enough data about the usage of tyre types on the road can lead to a better understanding of the consequences of studded tyres on the environment. This paper is focused on training and testing a machine learning model which can be further integrated into a larger system for automation of the data collection process. LÄS MER
