  1. 1. Control system framework for robots based on real-time application. : A proposed framework and dynamic sampling rate algorithm (DSRA) application in a robotic system for efficient data collection.

    Kandidat-uppsats, Linnéuniversitetet/Sjöfartshögskolan (SJÖ)

    Författare :Mugisha Steven; [2023]
    Nyckelord :Real-time application; Robots;

    Sammanfattning : Industry 4.0 is associated with the technological complexity of designing frameworks for factory automation. In that case, since the robots are used in factory operations, this paper proposes a framework that can be used for (near) real-time applications (RTA) in the robotic system. LÄS MER

  3. 2. 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

  4. 3. Development of method for early fault detection in small planetary gear sets in nutrunners

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Maskinelement

    Författare :Joakim Stenudd; [2021]
    Nyckelord :Condition monitoring; predictive maintenance; planetary gear; signal analysis; product development; fault detection; circular economy;

    Sammanfattning : The objective of this thesis work was to develop a method to detect early damage on small planetary gear sets that are installed in Atlas Copco nutrunners. The project has gone through several stages of product development, from idea to working product and signal analysis. LÄS MER

  5. 4. Micro-architectured materials for noise and vibration control in high voltage products – design and modelling

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad mekanik

    Författare :Alec Chamberlain; [2021]
    Nyckelord :Microarchitectured; lattice; elasticity; viscoelasticity; computational; homogenization;

    Sammanfattning : Many Hitachi ABB Power Grids (HAPG) products vibrate and emit noise, but legal limitations of these parameters fuel the development of energy absorption methods used on products. Methods such as Constrained Layer Damping (CLD). LÄS MER

  7. 5. Sökande efter radiovågor från skärzonen vid svarvning

    M1-uppsats, Högskolan i Gävle/Avdelningen för industriell ekonomi, industridesign och maskinteknik

    Författare :Safdari Firoz; Woldegiorgis Yonas; [2021]
    Nyckelord :Metal cutting; Turning; Adhesive wear; Electromagnetic radiation; Acoustic emission; Skärande bearbetning; Svarvning; Adhesiv förslitning; Akustisk emission; Elektromagnetiska vågor;

    Sammanfattning : Adhesive wear occurs when small surfaces of the cutting tool due to friction are micro-welded to the chips and removed from the tool surface. A hypothesis as to whywelding occurs is that an electric potential field arises which initiates a chemical reaction and then welding of the work material and the tool takes place in the cuttingzone.
