  1. 1. Framtagning av jämförande mät- och analysmetod för att studera komfort i barnvagnar : Ett arbete om hur komfort med avseende på vibrationerkan mätas och analyseras komparativt

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknik

    Författare :Mikael Törn; Noah Påhlsson; [2023]
    Nyckelord :Barnvagn; ISO-2631:1; ISO-10326:1; komfort; vibration; mätning; dataanalys; RMS; AMV;

    Sammanfattning : This study seeks to take a closer look at how to create a reliable and repeatable method for comparative measurement and analysis of comfort regarding vibrations in strollers.To achieve this goal the study has been divided in three questions that focuses on established standards and previous studies, a construction of a measurement method and finally a construction of a data analysis method.

  3. 2. Vibrations in a high frequency clt floor panel - Measurement, prediction and evaluation

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :André Wirthig; [2023]
    Nyckelord :Vibrations; High frequency floors; Sensitive equipment; Technology and Engineering;

    Sammanfattning : There is an increased need for floors that can accommodate different type of sensitive equipment [1]. Further, it is recommended to design these floors as high frequency floors (HFF) to be able to meet the stringent vibration criteria [1]. LÄS MER

  4. 3. Comfort of children in cycle carriers

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

    Sammanfattning : Carriers attached as bicycle trailers that can transport small children are becoming increasingly popular in recent years. They replace cars as a convenient and sustainable way to travel for families in commuting and other everyday activities. LÄS MER

  5. 4. Assessment of optimal suspension systems with regards to ride under different road profiles

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Adithya Murali; Pratik Hindraj Vaje; [2021]
    Nyckelord :Ride comfort; Handling; Road profiles; ADAMS; Shaping filter method; Sinusoidal approximation method; Coherence; ISO 8608; Acceleration PSD s; Genetic Algorithm optimisation; ISO 2631.; åkkomfort; Kurvkörningsegenskaper; Vägprofiler; ADAMS; Formningsfiltermetod; Sinusformad approximationsmetod; Koherens; ISO 8608; Acceleration PSDs; Genetisk algoritmoptimering.;

    Sammanfattning : Passenger ride vibration comfort is a critical aspect to consider while developing any vehicle and there is a need to understand how the occupants would be affected when driving on different road profile roughness. Hence, road profile generation is critical as road profiles are used as inputs to simulation tools to investigate vehicle dynamic behaviour in depth. LÄS MER

  7. 5. Predicting comfort in autonomous driving from vibration measurements using machine learning models

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Kate Asarar; [2021]
    Nyckelord :Passenger comfort; Machine learning; Autonomous driving; Vibrationer; Passagerarkomfort; Maskininlärning; Vibrationer; Självkörande bilar;

    Sammanfattning : Highly automated driving is approaching reality at a high speed. BMW is planningto put its first autonomous driving vehicle on the road already by 2021. The path torealising this new technology is however, full of challenges. LÄS MER
