  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.

    University essay from Linnéuniversitetet/Sjöfartshögskolan (SJÖ)

    Author : Mugisha Steven; [2023]
    Keywords : Real-time application; Robots;

    Abstract : 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. READ MORE

  3. 2. 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

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

    University essay from Luleå tekniska universitet/Maskinelement

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

    Abstract : 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. READ MORE

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

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Alec Chamberlain; [2021]
    Keywords : Microarchitectured; lattice; elasticity; viscoelasticity; computational; homogenization;

    Abstract : 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). READ MORE

  6. 5. Analytical Investigation of Planetary Gears Instabilities and the Impact of Micro-Macro Geometry Modifications

    University essay from KTH/Farkostteknik och Solidmekanik

    Author : Hamza Oudich; [2020]
    Keywords : Planetary gears; Instabilities; Resonance; Vibration; dynamic response; Spectral Iterative Method; Modal analysis; Static and dynamic transmission error; Gear mesh stiffness; Macro and micro-geometry; Phasing;

    Abstract : Due to their large torque-speed ratio and transmission efficiency, planetary gears are widely used in the automotive industry. However, high amplitude vibrations remain their critical weakness, which limits their usage especially when new strict noise legislations come into action. READ MORE
