1. Evaluating the roll performance of a hydraulic-interconnected suspension system for an electric bus
Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesignSammanfattning : Electric buses often have batteries installed on the roof structure to have a better space utilization. This increases the height of the centre of gravity of the vehicle, affecting its roll stability. The existing vehicle setup uses an anti-roll bar to provide the roll stiffness. LÄS MER
2. Evaluation of Active Rear Steering through Multi-Body Simulation
Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesignSammanfattning : The goal of this thesis work is to evaluate and quantify the advantages and disadvantages of Active Rear Steering (ARS). The evaluation is carried out through Multi-Body System (MBS) simulations. An analytical model has been developed to better understand the basic dynamics of vehicles equipped with rear steering.

3. Co-Simulation of Engine Model and Control System with focus on Turbocharger Model
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikSammanfattning : The demands on heavy duty vehicles is constantly raising with government legislations on CO2 emissions becoming stricter and increasing customer demands. A continuous search for new methods and tools is a crucial element in finding more performance and lower emissions, which are prerequisites for heavy duty vehicles of the future. LÄS MER
4. Implementation, Validation, and Evaluation of 1D-3D CFD Co-simulation for Cooling System of Internal Combustion Engine
Master-uppsats, KTH/FordonsdynamikSammanfattning : Internal combustion engines, electric motors and batteries generate a significant amount of heat during operation that needs to be extracted by cooling systems. A cooling system is designed and installed to extract the generated heat and maintain the system temperature in an optimal range. LÄS MER
5. Development and application of a multidomaindynamic model for direct steamgeneration solar power plant
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Nowadays, one of the solutions considered in order to face the issue of global warming and to move towards a carbon neutral society relies on the use of solar energy as a renewable and bountiful primary source. And, if photovoltaic technologies account for a large part in the solar energy market, recent years have witnessed the growth of non-concentrated and concentrated solar thermal technologies. LÄS MER
