  1. 1. 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.

  2. 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

  3. 3. Digital hydraulics in aircraft control surface actuation : Modelling and evaluation of digital hydraulic systems with focus on performance and energy efficiency

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

    Författare :Simon Ward; [2017]
    Nyckelord :dha; digital hydraulics; hydraulics; aircraft; actuation; aircraft actuation;

    Sammanfattning : The purpose of this thesis has been to compare and analyse the use of digital hydraulic actuators in place of traditional actuators in aircraft control surface manipulation. Digital hydraulic actuator referring to a hydraulic actuator where the power has been discretized using discrete on/off-valves. LÄS MER

  4. 4. Hydraulic hybrids

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Prithviraj Jaipal; [2017]
    Nyckelord :;

    Sammanfattning : Conventional IC Engine powertrain layouts in vehicles tend to consume considerable amounts of fuel and generate emissions that are harmful to the environment. Newer technologies have enabled the development of sustainable vehicle layout designs that favor a reduction in the exhaust emissions and energy consumption without compromising the vehicle’s performance.

  5. 5. Energy Efficient, Electric-Hydraulic Power Pack

    Master-uppsats, Linköpings universitet/FordonssystemLinköpings universitet/Tekniska fakulteten; Linköpings universitet/FordonssystemLinköpings universitet/Tekniska fakulteten

    Författare :Johan Nyman; Amy Rankka; [2015]
    Nyckelord :hybrid; hydraulic; electric; power pack; control; electro-hydraulic; loader crane;

    Sammanfattning : Along with increased oil prices and rising environmental issues, a demand for alternatives to combustion engine driven hydraulic applications has risen. In the field of mobile hydraulics, the hydraulic applications have traditionally been driven by the combustion engine of the vehicle on which they are mounted. LÄS MER
