1. 1. Simulation model refinement for Steer and Brake by Wire System : From Simulation Model to Hardware in the Loop

   Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

   Författare :Jeff Risi; Chandan Veera; [2023]
   Nyckelord :Steer-by-Wire; Brake-by-Wire; Real Time model; Hardware-in-the-loop; Mining machine; Fluid Power; Hydraulics; FLUMES;

   Sammanfattning : Simulation tools have progressed largely and in modern times they are commonly usedby engineers to design and simulate machines or part of machines before building and deploying them in the field. The field of Hardware-in-the-loop (HIL) is gaining significant interest among companies as they strive to enhance product safety and reliability simul-taneously reducing testing costs and accelerated development speed.

3. 2. Påldrivning: Jämförelse mellan luft- och vattendriven borrning : En utredning av jämförelser avseende slitage, logistik och driftkostnader

   Kandidat-uppsats, KTH/Byggteknik och design

   Författare :Andreas Bengtsson; Pierre Bodin; [2022]
   Nyckelord :: percussion hammer; pilot; DTH; pile driving; wear; drill rig; casing; piston; check valve; water-handling; sedimentation; : sänkhammare; pilot; DTH; pålning; slitage; borrigg; foderrör; kolv; backventil; vattenhantering; sedimentering;

   Sammanfattning : Skanska Grundläggning in Region Special wishes to gain an increased understanding of the extent to which it differs in the wear of percussion hammers and pilot drill crowns, depending on which driving medium is used in down-the-hole drilling, as well as logistical and economic aspects depending on the chosen method. Down-the-hole drilling means that the hammer works down in the borehole and forms one of the components at the far end of the drill string together with a drill bit. LÄS MER

4. 3. Installation of cables for monitoring purposes in the ground by using Horizontal Directional Drilling

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

   Författare :Eduardo Garcia Cañas; [2022]
   Nyckelord :HDD; Earth Embankment Dam; Resistivity; ERT; IP; Technology and Engineering;

   Sammanfattning : The median age for Swedish earth embankment dams is about 60 years. Due to its longevity, one of the major concerns is the internal erosion causing increased seepage through the dam, which ultimately may increases the risk for dam failure. To meet this challenge, there is a need for improved monitoring methods. LÄS MER

5. 4. Evaluation of Models and Optimisation Methods for Energy Minimisation of Drill Riggs

   Master-uppsats, Linköpings universitet/Fordonssystem

   Författare :Mohamed Faraj; Max Olsson; [2022]
   Nyckelord :Vehicle Propulsion Systems; Electrical powertrain; Modeling; Simulation; Deterministic dynamic programming; AMESim;

   Sammanfattning : There are many benefits from using electrical powertrains over diesel powertrains within the mining industries, where some of these benefits come from reducing the pollution within the mines and therefore improve the working environment as well as reduce the ventilation costs required from ventilating these pollution. It is also desired to optimise the use of the vehicle to increase the efficiency and reduce fuel consumption of the vehicle. LÄS MER

7. 5. Digital twin of a safe system

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

   Författare :Johan Edenhamn; [2022]
   Nyckelord :digital twin; safe system; hardware-in-the-loop HIL ; hydraulic model;

   Sammanfattning : At Epiroc’s drill rigs a safe system is installed to make sure the vehicle is driven in a safe manner. In the development both machine tests and hardware-in-the-loop (HIL) tests have been performed but when changes are made the firmware in the safe modules has to be updated. To speed up the process a digital twin would be beneficial. LÄS MER
