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

    Master-uppsats, 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. 2. Energy Management of Parallel Hydraulic Hybrid Wheel Loader

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

    Författare :Hoang Thai Do; [2018]
    Nyckelord :;

    Sammanfattning : Hybridization of driveline system is one possible solution to increase fuel eciency.In this thesis a parallel hybrid hydraulic wheel loader concept was studied. A highpressure accumulator was added to the system and acted as a second source of energy. LÄS MER

  4. 3. Finite Element Analysis of Osseointegrated Transfemoral Implant : Identification of how the Length of Implant Affects the Stress Distribution in Cortical Bone and Implant

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Anna Pogosian; [2018]
    Nyckelord :Osseointegrated; Implant; Transfemoral; Finite Element Methods;

    Sammanfattning : An alternative method of conventional prosthesis is  osseointegrated transfemoral implant, in where the prosthesis is fixated directly to the bone. The benefits with this system is increased range of motion, sensory feedback and reduced soft tissue problem. LÄS MER

  5. 4. Statistisk behandlig av driftsdata : Ur Garpenberggruvans driftcentral

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Byggteknik

    Författare :Eric Sjödén; [2014]
    Nyckelord :Processeffektivisering; Processvariation; Salvcykeltid; Aktivitetstid; Störning; Bergkvalitet;

    Sammanfattning : Boliden Mineral Ab's mine in Garpenberg, Dalarna is going through a massiveexpansion. The annual ore production is being increased from 1,4 million tons to 2,5million tons in less than two years period of time. LÄS MER

  7. 5. Identifying Operator Usage of Wheel Loaders Utilizing Pattern Recognition Techniques

    Master-uppsats, Fordonssystem; Tekniska högskolan

    Författare :Karin Ohlsson-Öhman; [2012]
    Nyckelord :;

    Sammanfattning : The information about how wheel loaders are used by costumers is not well documented, but large quantities of sensor signal data are recorded. This data makes the starting point to develop a robust automatic pattern recognition algorithm to identify repetitive driving operations. The algorithm is composed by models of events that appear in cycles. LÄS MER
