  1. 1. Analog mixed signal front-end for Torque signal processing : A theoretical noise analysis and signal-chain evaluation

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jesper Jansson; Wilhelm Nordgren; [2023]
    Nyckelord :Torque sensor; noise analysis; signal processing; analog-to-digital conversion; Momentgivare; brusanalys; signalbehandling; analog-till-digital omvandling;

    Sammanfattning : High precision tightening of nuts and bolts together with traceability are important in many industrial assembly lines. To achieve this the nutrunner needs to accurately measure the torque which is applied to the nut, process the signal and provide the information to the controller that controls the tightening process.

    Sammanfattning : Advanced bolt-tightening tools such as automatic nutrunners are commonly used in industrial factories to streamline the assembly process. In safety-critical systems, it is crucialto control the tightening process. LÄS MER

  4. 3. Climate Impact of a Nutrunner

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

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

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Simon Carlsson; [2020]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

  7. 5. Model parameter estimation for a handheld nutrunner

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Jonathan Fridstrand; Johanna Sturk; [2020]
    Nyckelord :;

    Sammanfattning : 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.
