  1. 1. Predicting Location-Dependent Structural Dynamics Using Machine Learning

    University essay from KTH/Industriell produktion

    Author : Markus Zink; [2022]
    Keywords : machine learning; artificial intelligence; gradient boosting; LightGBM; multilayer perceptron; prediction; chatter; vibration; structural dynamics; modal parameters; machine tool; tool centre point; work envelope;

    Abstract : Machining chatter is an undesirable phenomenon of material removal processes and hardly to control or avoid. Its occurrence and extent essentially depend onthe kinematic, which alters with the position of the Tool Centre Point, of the machine tool. READ MORE

  3. 2. Model verification and common mode current analysis of grid connected three phase two level converters

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Simon Lindvall; Richard Haraldsson; [2021]
    Keywords : active filter; EMC; EMI; converter; common mode; differential mode; shunt active filter; parasitic elements; Technology and Engineering;

    Abstract : In this Master’s thesis an in-depth model of a shunt active filter for high frequency analysis is constructed. The purpose is to enable analysis of higher frequency behavior reaching 1MHz. Using the high frequency model, common mode currents can be simulated. READ MORE

  4. 3. Comparative study of the static and quasi-static compliance measurement procedures on industrial manipulators

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

    Author : Katrin Kersch; Anwar Ahmad Rana; [2021]
    Keywords : industrial manipulators; stiffness; compliance calibration; pose accuracy; Industriella manipulatorer; stelhet; efterlevnadskalibrering; positionsnoggranhet;

    Abstract : Serial articulated industrial manipulators are increasingly used in machining applications due to their flexibility in application and their cost-effectiveness compared to conventional machinery. However, the use of industrial manipulators in machining processes that subject the robot to high loads such as in drilling is limited. READ MORE

  5. 4. Dynamic Torque Modeling of a Wet Lamella Clutch Pack

    University essay from Lunds universitet/Industriell elektroteknik och automation

    Author : Jacob Wallersköld; Johan Appelros; [2021]
    Keywords : wet lamella clutch; friction modeling; torque modeling; torque accuracy; force measurements; system identification; grey-box modeling; Technology and Engineering;

    Abstract : Wet lamella clutches are used in the automotive industry to enable all-wheel drive and thereby increase acceleration, handling and safety of cars. The clutches work by transmitting torque from an incoming- to an outgoing shaft through a series of lamella - steel-disc friction surfaces (lamella pack), lubricated by an oil. READ MORE

  6. 5. Experimental Investigation of Fluid-added Parameters on a Kaplan Runner

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Malin Strandberg; [2021]
    Keywords : Added mass; added inertia; fluid dynamics; hydropower; Kaplan turbine; fluid-solid interaction;

    Abstract : In order to reach climate and environmental goals, Sweden is increasing the implementation of intermittent renewable energy sources such as wind and solar power to the electricity grid. The increase of intermittent energy sources is rising power regulation requirement towards hydropower, which increasingly exposes the hydraulic turbines to high loads and fluctuating hydraulic forces.
