  1. 1. Implementation and integration of slip and traction controllers for a three-wheel electric vehicle

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Blanca Zumárraga; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The purpose of the Master Thesis is, on one hand, to develop a traction control system, integrating and implementing two controllers in the vehicle, each of them previously designed and tested separately, to test them together to evaluate their performance. On the other hand, to develop accurate and well-performing controllers, the data acquisition needs to be precise so parameters and devices need to be tuned again, because of small modification in the structure of the vehicle.

  3. 2. Design Study of Welded Beam Bracket According to Stress Concentrations in the Weld

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :FREDRIK EKLUND; [2021]
    Nyckelord :Plug weld; slot weld; welded beam; welded beam bracket; welded bus chassis; Pluggsvets; svetsad balk; svetsad busschassi; svetsad ram;

    Sammanfattning : In a bus chassis, welded connections are often preferred to other fastening techniques due to low cost and broad competence among suppliers but are usually the weakest parts due to fatigue life. Evaluation of welds is often costly in time and competence. LÄS MER

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

    Master-uppsats, KTH/Marcus Wallenberg Laboratoriet MWL

    Författare :Riccardo Derton; [2021]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 4. Strategies for Road Profile in Adaptive Suspension Control

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Fredrik Skoglund; [2020]
    Nyckelord :;

    Sammanfattning : Semi-active suspension systems has become an increasingly popular alternative to the passive suspensions in recent time. By varying the spring stiffness and damping coefficient in the system, different characteristics can be achieved depending on driver preferability and road disturbances. LÄS MER

  7. 5. Dynamic Analysis of an Automotive Power Transfer unit : Towards prediction of TE and housing vibrations

    Master-uppsats, KTH/Maskinkonstruktion (Avd.)

    Författare :Nikhil Maharshi Kosaraju; [2019]
    Nyckelord :Power transfer unit PTU ; Multi-Body Simulation MBS ; Transmission Error; Gear NoiseVibration; Modal Analysis; Vinkelväxlen PTU ; Multi-Body Simulering MBS ; transmissionsfel TE ; Växelljud och vibrationer; Modal analys;

    Sammanfattning : This work describes the use of Multi-Body Simulation (MBS) to create a virtual prototype of a geared drive called Power transfer unit (PTU). PTU is a subsystem of the all-wheel drive driveline responsible for transfer of power between front and rear axles in an Automobile. LÄS MER
