  1. 11. Evaluating the roll performance of a hydraulic-interconnected suspension system for an electric bus

    University essay from KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Author : Dinesh Ramachandran; [2021]
    Keywords : Electric bus; Centre of Gravity; Roll gradient; Hydro-pneumatic suspension; Multi-body simulations; Co-simulation; Elektrisk buss; Tyngdpunkt; krängningsgradient; Hydro-pneumatisk fjädring; Flerkroppssimuleringar; Co-simulering;

    Abstract : Electric buses often have batteries installed on the roof structure to have a better space utilization. This increases the height of the centre of gravity of the vehicle, affecting its roll stability. The existing vehicle setup uses an anti-roll bar to provide the roll stiffness. READ MORE

  2. 12. Modelling of contacts in Adams flex bodies using Mamba

    University essay from KTH/Fordonsdynamik

    Author : Shashwat Joshi; [2021]
    Keywords : Contact simulation; Mamba; Joint Interface Modes; Leaf spring modelling; Frame-subframe contact; ODS analysis; PSD; Kontaktsimulering; Mamba; gemensamma gränssnittslägen Joint Interface Modes ; bladfjädermodellering; ram-subramkontakt; ODS analys; PSD;

    Abstract : Simulations are a powerful tool used to reduce development time and cost in the vehicle industry. However, the models used in simulations are simplifications of reality, and there are commonly contradicting requirements between accuracy and computational efficiency. READ MORE

  3. 13. Enhancing the endurance of UAVs by the use of structural power composites: System-level study of a flying wing

    University essay from KTH/Lättkonstruktioner

    Author : Gustav Burman; [2021]
    Keywords : ;

    Abstract : This thesis studies the feasibility of integrating the novelStructural Battery (SB)[1] into the airframe of a UnmannedAerial Vehicle (UAV). The potential advantages in terms ofmass, range and endurance are studied.The aircraft performance is analysed using conventionalflight mechanics, modelled in Matlab and Xfoil. READ MORE

  4. 14. Door closing sound quality related to door sealing stiffness

    University essay from KTH/Marcus Wallenberg Laboratoriet MWL

    Author : Riccardo Derton; [2021]
    Keywords : Door Closing Sound Quality; Customer’s Perspective; Psychoacoustics; Acoustic Analysis; Wavelet Analysis; Artificial Head; Door Closing Motion; Door Seals; Door Sealing Stiffness; Stiffness Analysis; Ljudkvalitet vid dörrstängning; Kundperspektiv; Psykoakustik; Akustisk analys; Wavelet analys; Konstgjort huvud; Dörrstängningsrörelse; Dörrtätningar; Styvhet i dörrtätningar; Styvhetsanalys;

    Abstract : The door closing action is a recurrent situation when using a vehicle, and its sound is therefore a common sensation, which would elicit pleasant feelings. Sensory pleasantness is an important aspect in terms of customer’s perspective, and it can be a contributing factor when deciding to buy or not a specific vehicle. READ MORE

  5. 15. Rear end crash simulation using Human Body Models : An investigation of the design of seat structure using a 50th percentile female Human Body Model

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Jacob Fagerström; [2020]
    Keywords : Human body model; Car crash; Finite element method;

    Abstract : In this master thesis it have been investigated how the stiffness of a seat affect the risk of neck injuries, e.g whiplash associated disorders, in a rear end low velocity car collision using a female human body model, HBM, and if dividing the seat into several sections with different stiffnesses.
