  1. 21. Automatic data processing of traction motor measured data and vibration analysis of test bench

    University essay from Uppsala universitet/Institutionen för elektroteknik

    Author : Arshey Dhangekar; [2021]
    Keywords : Electric motor; Traction motor; MATLAB; data processing; data analysis; COMSOL Multiphysics; FEM; test bench; natural frequency;

    Abstract : One of the goals of ABB AB is to develop highly efficient electric motors for traction application. The demand for traction motors is increasing due to the rise in electric vehicles sale and railway locomotive engines. READ MORE

  3. 22. 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

  4. 23. Active stabilisation of a micro-sized fibre cavity using tilt locking to enable quantum operations on single ions

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Jannek Hansen; [2021]
    Keywords : Quantum computation; optical cavity; microcavity; locking; tilt locking; cavity stabilization; Gaussian-Hermitian modes; quantum computer; higher-order transverse modes; Physics and Astronomy;

    Abstract : In this thesis, the tilt locking scheme is applied to create an error signal that monitors length changes in a fibre-based microcavity. To find a robust and precise locking technique is an essential step towards quantum operations on single rare-earth ions doped in microcrystals. Quantum computing and information is a frontier of modern physics. READ MORE

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

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Srujeeth Khanna Bala; [2021]
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 25. Test Equipment for Physical Testing of Vibration Isolator

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : ADAM ALVETEG; MARKUS JOHANSSON; [2021]
    Keywords : Test rig; vibration isolator; hysteresis; Testrigg; vibrationsisolator; hysteres;

    Abstract : Vibrations is a phenomenon that can cause problems to systems if not dealt with. In heavy duty trucks, vibrations are mainly caused by uneven roads and from the combustion engine. Vibrations can damage components, reduce their service life and cause discomfort for the driver.
