  1. 1. Climate Impact of a Nutrunner

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Nicole Holmgren; [2022]
    Keywords : Carbon footprint; life cycle assessment; nutrunner; Klimatavtryck; livscykelanalys; mutterdragare;

    Abstract : Climate change is an existential threat to the world, causing environmental degradation and destruction of ecosystems. The EU acknowledges that several alarming tipping points are about to be reached, and the current level of action is not enough to avert global warming. READ MORE

  3. 2. Anomaly Detection using LSTM N. Networks and Naive Bayes Classifiers in Multi-Variate Time-Series Data from a Bolt Tightening Tool

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

    Author : Karl-Filip Selander; [2021]
    Keywords : LSTM; anomaly detection; time-series; multi-variable; sensor; deep learning; LSTM; anomalidetektion; tidsserie; multivariabel; sensor; djupinlärning;

    Abstract : In this thesis, an anomaly detection framework has been developed to aid in maintenance of tightening tools. The framework is built using LSTM networks and gaussian naive bayes  classifiers. The suitability of LSTM networks for multi-variate sensor data and time-series prediction as a basis for anomaly detection has been explored. READ MORE

  4. 3. Wireless Power and Data Transfer in Industrial Nutrunners

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Simon Carlsson; [2020]
    Keywords : ;

    Abstract : Wireless power and data transfer systems are experiencing an ever-growing consumer and industrial adoption. Its use in common devices has made the technology more accessible to people, but seldomly does it replace a physical connection inside a product. READ MORE

  5. 4. Model parameter estimation for a handheld nutrunner

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Jonathan Fridstrand; Johanna Sturk; [2020]
    Keywords : ;

    Abstract : The purpose of this project is to investigate the angled nutrunner, which is a hand held torque tool often used in the industry to tighten bolted joints. The goal is to estimate parameter values for an existing model that can describe the reaction force and the angular displacement of the tool as a function of the torque transferred to the joint.

  6. 5. Planetary Gear Analysis : deformation induced misalignment and optimization

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Martin Jonsson; [2020]
    Keywords : FEM; gears; KISSsoft; misalignment; planetary gears; FEM; KISSsoft; kugghjul; planetväxlar; vinkelfel;

    Abstract : A handheld heavy-duty nut runner, commonly used to assemble windmills and oil pipe lines, and capable of producing 4100 Nm of torque, experiences low cycle fatigue and usually fails after 20 000 cycles at the specified torque. A full assembly Finite element model of the last stage of the four-stage planetary gearbox is constructed and simulated over one complete load cycle. READ MORE
