  1. 1. Energy Consumption and Running Time for Trains modelling of running resistance and driver behaviour based on full scale testing

    University dissertation from Stockholm : KTH

    Author : Piotr Lukaszewicz; KTH.; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy consumption; Running time; running resistance; driver behaviour; freight; train; energy coasting method; aerodynamic drag; driver model; degree of coasting; slippage; wind; Energy saving; braking ratio; powering ratio; full scale testing; TECHNOLOGY Engineering mechanics Vehicle engineering; TEKNIKVETENSKAP Teknisk mekanik Farkostteknik;

    Abstract : The accuracy in determined energy consumption and runningtime of trains, by means of computer simulation, is dependent upon the various models used. This thesis aims at developing validated models of running resistance, train and of a generaldriver, all based on full scale testing. READ MORE

  2. 2. Ride comfort and motion sickness in tilting trains

    University dissertation from Institutionen för farkostteknik

    Author : Johan Förstberg; KTH.; [2000]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tilting train; Ride comfort; Motion sickness; Simulator; Experiments;

    Abstract : This thesis presents a systematic study of human responses to different motions and strategies of car body tilt control regarding ride comfort, working/reading ability and motion sickness on high-speed tilting trains. Experiments with test subjects were performed in a tilting train on curved track as well as in a moving vehicle simulator. READ MORE

  3. 3. Exhaust Heat Utilisation and Losses in Internal Combustion Engines with Focus on the Gas Exchange System

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Habib Aghaali; KTH.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbocharger; heat transfer; heat loss; exhaust heat utilisation; waste heat recovery; turbocompound; divided exhaust period; internal combustion engine; gas exchange; pumping loss; variable valve timing; WHR; DEP; Turbo; värmeöverföring; värmeförluster; avgasvärme utnyttjande; förluster vid värmeåtervinning; turbocompound; delad avgasperiod; förbränningsmotor; gasväxling; pumpningsförlust; variabla ventiltider; WHR; DEP; Farkostteknik; Vehicle and Maritime Engineering; Energiteknik; Energy Technology;

    Abstract : Exhaust gas energy recovery should be considered in improving fuel economy of internal combustion engines. A large portion of fuel energy is wasted through the exhaust of internal combustion engines. Turbocharger and turbocompound can, however, recover part of this wasted heat. READ MORE

  4. 4. Application of a Sandwich Construction on a Superstructure of a High Speed Ferry

    University dissertation from Chalmers University of Technology

    Author : Gaurav Ahuja; Chalmers tekniska högskola.; Chalmers University of Technology.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Farkostteknik; Vehicle engineering; Konstruktionsteknik; Construction engineering; Sandwich construction; light weight structure; catamaran; carbon fibre; glass fibre; finite element analysis; natural frequency analysis; torsional moment; pitch connecting moment; structural optimisation.;

    Abstract : Usage of light weight materials has gained momentum in the marine market in the last few decades. This rise has lead to some ships using parts fabricated out of materials like glass and carbon fibre. READ MORE

  5. 5. Engine Thermal Management in Heavy Duty Vehicles

    University dissertation from Chalmers University of Technology

    Author : Arne Andersson; Chalmers tekniska högskola.; Chalmers University of Technology.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Farkostteknik; Vehicle engineering; Strömningsmekanik; Fluid mechanics; Heat Transfer; Heat Exchangers; Turbomachinery; Thermal Management; Control Simulation;

    Abstract : Future regulations on noise and exhaust emissions have a large impact on heavy duty engine installations. Cooled EGR is used for NOx abatement. Better sealed engine encapsulations are used to meet new noise regulations. Engine thermal management is therefore becoming an increasingly important discipline. READ MORE
