  1. 1. Investigating User Accepted Interaction Concepts for Autonomous Mining Vehicles : A Design Process for Developing and Validating a Human-Machine Interaction Concept based on User Needs

    University essay from Linköpings universitet/Interaktiva och kognitiva system

    Author : Johan Rindborg; Johanna Engström; [2021]
    Keywords : ;

    Abstract : As autonomous vehicles (AVs) are introduced in mining settings, mine workers must adapt to a new type of workflow. This thesis presents how a design process for developing and validating a user accepted Human-Machine Interaction (HMI) concept in an autonomous mining environment can be performed. READ MORE

  3. 2. Impact of model accuracy on the performance of an optimization-based path planning algorithm for an articulated vehicle

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

    Author : Deyuan Chen; Zhiqiang Yang; [2019]
    Keywords : ;

    Abstract : This thesis presents a study on how the accuracy of vehicle kinematic models can affect the performance of an optimization-based path planner. A bicycle model and an articulated machine model are chosen to be different accurate levels of modelling. The path planner generates a final path in two steps. READ MORE

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

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

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

    Abstract : 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.

  5. 4. Machine Learning for Activity Recognition of Dumpers

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

    Author : Henrik Axelsson; Daniel Wass; [2019]
    Keywords : Civil engineering; earth-moving; dumper; machine learning; naive bayes; random forest; neural networks; smartphone sensors; accelerometer; gyroscope.;

    Abstract : The construction industry has lagged behind other industries in productivity growth rate. Earth-moving sites, and other practices where dumpers are used, are no exceptions. Such projects lack convenient and accurate solutions for utilization mapping and tracking of mass flows, which both currently and mainly rely on manual activity tracking. READ MORE

  6. 5. Simulation of an Electric Quarry with Automated Transporter Scheduling

    University essay from KTH/Optimeringslära och systemteori

    Author : Bilin Chen; Ida Karlsson; [2018]
    Keywords : ;

    Abstract : An electric site project is being developed by Volvo Construction Equipment with the goal to transform the quarry and aggregate industry by reducing carbon emissions by up to 95 % and total ownership cost up to 25 %. The goal is achieved by using electrical autonomous vehicles as the work force. READ MORE
