  1. 1. Machine vision for automation of earth-moving machines : Transfer learning experiments with YOLOv3

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Carl Borngrund; [2019]
    Nyckelord :Machine learning; Machine vision; YOLOv3; You only look once; Computer vision; Real time object detection; Object detection;

    Sammanfattning : This master thesis investigates the possibility to create a machine vision solution for the automation of earth-moving machines. This research was done as without some type of vision system it will not be possible to create a fully autonomous earth moving machine that can safely be used around humans or other machines.

  2. 2. Control of a Hydraulic Hybrid System for Wheel Loaders

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system; Linköpings universitet/Fluida och mekatroniska system

    Författare :Christopher Reichenwallner; Daniel Wasborg; [2019]
    Nyckelord :EMS; Energy management strategy; Rule-based; Hydraulic hybrid; Wheel loader; Construction machinery; SLC; Short loading cycle; Torque converter; Energy recuperation; Energy efficiency; Backward simulation;

    Sammanfattning : In recent years many companies have investigated the use of hybrid technology due to the potential of increasing the driveline’s efficiency and thus reducing fuel consumption. Previous studies show that hydraulic hybrid technology can be favourable to use in construction machinery such as wheel loaders, which often operate in repetitive drive cycles and have high transient power demands.

  3. 3. FE based method for simulation of rock-loading on a truck

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik; Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Tamim Kohestani; Ali Zeaiter; [2019]
    Nyckelord :FEM; Rock loading; Nastran; LS-DYNA; ANSA; META; Contact; Linear; non-linear; Explicit; Implicit.;

    Sammanfattning : Volvos trucks are used to carry boulders of varying sizes from different mining sites or construction sites. These boulders are loaded onto the dumper of the truck by a wheel-loader which drops the boulders from various heights causing an impulse like force which distributes throughout the frame and to the rest of the truck.

  4. 4. Utveckling av en fördelningsväxellåda till hjullastare

    Master-uppsats, Mälardalens högskola/Akademin för innovation, design och teknik; Mälardalens högskola/Akademin för innovation, design och teknik

    Författare :Tony Franzén; Daniel Ekberg; [2019]
    Nyckelord :Dumper; Fördelningsväxellåda; Hjullastare; Konstruktion;

    Sammanfattning : The thesis is a case study on the construction of a dropbox for wheel loaders. The thesis was carried out at Volvo Construction Equipment (VCE) who is one of the leading manufacturers of construction equipment. The data collection consisted of a pre-study, a literature review, and simulations and calculations, which was done at VCE. LÄS MER

  5. 5. En jämförande studie mellan diesel- och eldrivna tunneldrivningsmaskiner för masshantering i tunnel

    M1-uppsats, KTH/Byggteknik och design; KTH/Byggteknik och design

    Nyckelord :Tunnel construction; Shot rock; Electrically powered; Carbon dioxide emissions; Energy consumption; Costs Truck; Wheel loader; Tunnelbyggnation; Bergmassor; Eldrivet; Koldioxidutsläpp; Energiförbrukning; Kostnader; Lastbil; Hjullastare;

    Sammanfattning : The construction industry is facing a reality where the dependency on fossil fuels needs to cease and be replaced by options that are more climate friendly. One such option is the electrification that has not made a breakthrough in the construction industry yet and therefore needs to be examined. LÄS MER
