1. 1. Evaluation of Numerically Developed Models of an ECB for Estimating the Braking Torque on the SkiCrosser

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Filip Andersson; William Marin; [2023]
   Nyckelord :;

   Sammanfattning : Cross-country skiing is a popular method of exercising that builds strength, stamina and engages the entire body. As cross-country skiing requires snow to be present, it is typically only performed during the winter, resulting in a rather limited way of exercising. LÄS MER

3. 2. Process monitoring of turbine blades : Monitoring of blade tip clearance using eddy current sensors

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Hampus Andersson; [2022]
   Nyckelord :Blade tip clearance; Blade tip timing; Eddy current sensor; Turbine monitoring; Maintenance.; Bladtoppspel; Bladvibrationer; Eddy current sensorer; Turbinövervakning; Underhåll.;

   Sammanfattning : This thesis has been a collaboration between the Royal Institute of Technology (KTH) and Siemens Energy which invest in the research facility at KTH. The objective was to investigate the use of eddy current sensors in real-time monitoring of turbine blades. LÄS MER

4. 3. Stamping Condition Monitoring : A complete measuring and process control system for Husqvarna Edge

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Theodor Johansson; [2022]
   Nyckelord :condition monitoring; Stamping; Shut height; automation; Pressing; Sensors; Inductive sensors; Process control;

   Sammanfattning : The project covers the substitution of a stamping shut height measurement at the chainsaw chain factory Husqvarna Edge, with a new sensor-based processmonitoring system, set to increase productivity and decrease running costs. The workflow covers the span from external and needs analysis to development and testing of both hardware and software, in conjunction with communication with external suppliers to find the most usable and profitable solution going forward.

5. 4. Direct Sampling of the Pulsed Eddy Current Response From Non-Ferromagnetic Metals

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

   Författare :Sara Holmér; [2021]
   Nyckelord :;

   Sammanfattning : The non-destructive testing method Pulsed Eddy Current, or PEC, can be used to measure the thickness and resistivity of conducting and non-ferromagnetic materials. In this project I investigated if a gauge at ABB, which uses PEC technology to measure the thickness of aluminium strips in rolling mills, can extract more information about the strip by sampling the direct signal with a higher resolution than before.

7. 5. Measuring resistivity in a contactless fashion

   Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Författare :Jim Klintrup; [2020]
   Nyckelord :resistivity; magnetic; field; diffusive; eddy; current; coils; Physics and Astronomy;

   Sammanfattning : The aim of this thesis work was to develop a rig to measure the resistivity of a metal sample. The initial testing of the rig would be done at room temperature and calibration of the setup would be done with aluminum samples and then metallic alloys would be studied. LÄS MER
