  1. 1. Estimation of Blocked Forces in an Assembly with Rear Drive Unit as a Source

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Srujeeth Khanna Bala; [2021]
    Nyckelord :Component based TPA; source characterized forces; FEM; Contact forces; ISO20270:2019; Blocked forces; Automotive; NVH; sound and vibration; komponentbaserad TPA; karaktärisering av bullerkällor; FEM; kontaktkrafter; blockerade krafter; bilindustri; ljud och vibrationer; ISO20270:2019;

    Sammanfattning : Experimental validations are widely used for studying dynamic structural behaviors and these studies involve defining the structures completely as being used in real time. While in numerical simulations such detailed features are not specified to ease the computation, thereby deviating from accurate results. LÄS MER

  3. 2. Refined model for calculating the dynamic amplification factor for road bridges

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

    Författare :Jens Bergenudd; [2020]
    Nyckelord :Dynamics; Dynamic amplification factor; Dynamic impact factor; Platooning; Soil-structure interaction; Vehicle-bridge interaction; Technology and Engineering;

    Sammanfattning : The objective of the thesis is to simulate and evaluate vehicle-bridge interaction (VBI) due to road surface irregularities and soil-structure interaction (SSI) with different vehicle models and suspension properties. Parameter studies will be carried out for integral and slab bridges. LÄS MER

  4. 3. Deformering av kuggar i planetväxlar

    Uppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Tareq Alhasan; Adis Gredelj; [2020]
    Nyckelord :Robot; Planetväxel; Glappfritt; Kugghjul; Kontaktkraft; Kontaktstyvhet; SolidWorks; MSC Adams; kuggform.;

    Sammanfattning : Företaget SwePart i Liatorp har tagit fram en prototyp på en planetväxel utan glapp vilken kan gynna bl.a. robotindustrin. Problematiseringen är att växeln låter illa vid rotation vilket är vad som ska studeras i detta arbete. LÄS MER

  5. 4. Cartesian Force Estimation of a 6-DOF Parallel Haptic Device

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

    Författare :Fanghong Dong; [2019]
    Nyckelord :Haptic device; Cartesian force estimation; force torque sensor;

    Sammanfattning : The haptic device recreates the sense of touch by applying forces to the user. Since the device is “rendering” forces to emulate the physical interaction, the force control is essential for haptic devices. LÄS MER

  7. 5. Model Based HandlingAnalyses

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Paolo Perinciolo; Eshwar Sondhi; [2018]
    Nyckelord :;

    Sammanfattning : The thesis consists of building vehicle models for lateral dynamics that provide accurate results, while being simple enough to highlight clear relationships between vehicle properties and handling behaviours. The approach that characterizes the present work is built on the foundations provided by the bicycle, or single-track, model (STM). LÄS MER
