  1. 1. Analysis of the energy consumption of the powertrain and the auxiliary systems for battery-electric trucks

    University essay from KTH/Fordonsdynamik

    Author : Guanqiao Song; [2020]
    Keywords : Battery-electric truck; Energy consumption analysis; Battery loss; PT1 battery model; Power Take Off; Sankey diagram; Direct-Current charging; Batterielektrisk lastbil; Energiförbrukningsanalys; Batteriförlust; PT1 batterimodell; Power Take Off; Sankey diagram; Direct-Current charging;

    Abstract : The electrification of the truck is crucial to meet the strategic vision of the European Union (EU) to contribute to net-zero greenhouse gas emissions for all sectors of the economy and society. The battery-electric truck is very efficient to reduce the emissions and has also a lower Total Cost of Ownership (TCO) compared to diesel trucks. READ MORE

  2. 2. Introduction of a Sustainable Alternative for Bitumen : Case study of lignin-based asphalt for the Swedish market

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013); Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Shkar Hashmi; Ahmed Jabary; [2020]
    Keywords : lignin; asphalt; bitumen; procurement; market; sustainability; lignin; asfalt; bitumen; offentlig upphandling; marknad; hållbarhet;

    Abstract : For some time, sustainability has been the major principle of development across the globe, and all aspects of society are somehow affected by the concept. Companies are faced with stricter regulations and are forced to look for solutions to reduce their environmental impact. READ MORE

  3. 3. TWIST : Twelve Bar Intelligently Simulated Tensegrity

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Hannah Petersson; [2019]
    Keywords : tensegrity; robotics; simulations; monte carlo method; central pattern generators; lander; space;

    Abstract : One of the biggest challenges of putting a robot on an extraterrestrial surface is the entry, descent and landing. By making the robot impact resistant, the need for landing thrusters and parachutes is reduced, lowering the weight and cost of an interplanetary robotic mission. READ MORE

  4. 4. Shock Absorbing Flooring For Elderly Homes : Study of Shock Absorption of Head Impacts and Rolling Resistance

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Brynjar Hilmarsson; [2018]
    Keywords : Shockabsorbing Flooring; Rolling Resistance; Fall Injuries; Head Impact Studies;

    Abstract : In Sweden fall-related injuries among the elderly lead to over a thousand deaths and close to 300.0000 hospital visitations annually. Fall related injuries can in many cases lead to serious head injuries along with other fractures. The elderly are more prone to fall and sustain an injury because of conditions such as osteoporosis and weak muscles. READ MORE

  5. 5. Energy efficient cornering : Simulation and verification

    University essay from KTH/Fordonsdynamik; KTH/Fordonsdynamik

    Author : Nicolas Luco; Keren Zhu; [2018]
    Keywords : Bicycle model; Energy consumption; Vehicle cornering behaviour; Yaw moment control;

    Abstract : The purpose of this master thesis is to study the energy efficiency of a vehicle when it is cornering. To achieve this, a Simulink model was built from a simple basic bicycle model and theoretically validated. This model was then analysed and successively improved by adding velocity and yaw moment control. READ MORE
