  1. 1. Modelling and simulation of vibratory driven sheet piles - Development of a stop criterion

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Johannes Jonsson; Anton Andersson; [2021]
    Keywords : Vibratory driving; sheet pile; Technology and Engineering;

    Abstract : During excavations, steel sheet piles are often installed through vibratory driving, to establish a retaining wall that resists soil instability and ground water leakage. The method of vibratory driving is that the sheet pile is driven into the soil with a vertical vibratory motion. This is especially effective in soft soils. READ MORE

  3. 2. Investigation of the transient nature of rolling resistance on an operating Heavy Duty Vehicle

    University essay from Umeå universitet/Institutionen för fysik

    Author : Petter Lundberg; [2014]

    Abstract : An operating vehicle requires energy to oppose the subjected driving resistances. This energy is supplied via the fuel combustion in the engine. READ MORE

  4. 3. Study on optimal train movement for minimum energy consumption

    University essay from Akademin för innovation, design och teknik

    Author : Panagiotis Gkortzas; [2013]
    Keywords : Optimal control; train energy consumption; dynamic programming; Hamilton-Jacobi-Bellman equation;

    Abstract : The presented thesis project is a study on train energy consumption calculation and optimal train driving strategies for minimum energy consumption. This study is divided into three parts; the first part is a proposed model for energy consumption calculation for trains based on driving resistances. READ MORE
