  1. 1. Evaluation of bonding and maternal behaviours in cattle : swedish dairy cows in a cow-calf contact system

    Master-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Elin Svensson; [2022]
    Nyckelord :cow-calf contact; cow-calf bonding; maternal behaviours; preference test; dairy production;

    Sammanfattning : In today’s commercial dairy production, it is common practice to separate the cow and calf a few hours after parturition. There is, however, increased interest from both farmers and consumers, to keep the cow and calf together for a longer period while still maintaining dairy production, because it is perceived as more animal friendly.

  3. 2. Estimation of blocked forces from a rear drive unit (RDU) in a test rig fixture

    Master-uppsats, KTH/Teknisk akustik

    Författare :Sanjay Jayachandran; [2022]
    Nyckelord :Acoustics; Vibration; Sound; Mechanics; Blocked Forces; Transfer Path Analysis; Component-based TPA; Vibro-acoustics;

    Sammanfattning : In the modern world, vehicle manufacturers are not the sole producer of every component in a vehicle but instead assign different subsystems to various OEMs (Original Equipment Manufacturer). Subsystems such as Rear Drive Units (RDU), Power Transfer Units (PTU), E-drives etc. are developed separately and then integrated into the main vehicle. LÄS MER

  4. 3. 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

  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
