  1. 6. NVH analysis and optimization of electric powertrain

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Anujit Dafle; [2022]
    Keywords : Electric powertrain; Gear whine; Noise Vibration Harshness NVH ; Elektrisk drivlina; kuggvin; buller och vibrationer;

    Abstract : With increasing focus on electromobility many companies are developing vehicles powered by an electric energy source. Previously, engines used to be the most prominent source of noise in a traditional Internal Combustion Engine (ICE) vehicle. READ MORE

  3. 7. Requirements and Analysis of an Overload Protection Mechanism for an Electromechanical Linear Actuator

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Mats Vesterberg; [2022]

    Abstract : Cascade Drives specializes in high-performance electromechanical linear actuators (EMA). The company has developed a range of linear rack and pinion actuators based on a patented load distribution technique that allows multiple pinions to interact with a single gear rack. READ MORE

  4. 8. Design of an excavator grip : A pilot study and development of an ergonomic Human-Machine interface for excavators

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : Hugo Mörtsell; [2022]
    Keywords : Excavator Joystick; Excavator Grip; Excavator Control System; Industrial Design Engineering; Human Centered Design; Human-machine Systems; Operator Controls Ergonomics; Grävmaskin Joystick; Grävmaskin Styrsystem; Industriell Designteknik; Människocentrerad Design; Människa-maskin-system; Förarreglage Ergonomi;

    Abstract : The Excavator industry is developmentally behind many other similar industries. This is, like many parts of these long living machines, true for the controls used to maneuver them. It has few competent control systems that are ergonomic, comfortable, adaptable, durable and intuitive. READ MORE

  5. 9. A bonded discrete element approach to simulate loading with hydraulic mining excavators

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Carl Andersson; [2021]
    Keywords : DEM; bonded DE; granular material; hydraulic excavator; wear; Archard s wear law; LS-DYNA; simulation;

    Abstract : When operating hydraulic mining excavators the loading equipment is exposed to harsh conditions which lead to extensive wear of the equipment, especially the bucket and bucket teeth. Simulations are used to better understand the wear development and to evaluate new methods to operate excavators more efficiently. READ MORE

  6. 10. Controlling a Hydraulic System using Reinforcement Learning : Implementation and validation of a DQN-agent on a hydraulic Multi-Chamber cylinder system

    University essay from Linköpings universitet/Fluida och mekatroniska system

    Author : David Berglund; Niklas Larsson; [2021]
    Keywords : Gear selection; reinforcement learning; machine learning; DQN; neural network; multi chamber cylinder; Digital hydraulics; hydraulics; Matlab; Simulink; Hopsan; hydraulic system validation;

    Abstract : One of the largest energy losses in an excavator is the compensation loss. In a hydraulic load sensing system where one pump supplies multiple actuators, these compensation losses are inevitable. READ MORE
