1. 6. Analytical Investigation of Planetary Gears Instabilities and the Impact of Micro-Macro Geometry Modifications

   University essay from KTH/Farkostteknik och Solidmekanik

   Author : Hamza Oudich; [2020]
   Keywords : Planetary gears; Instabilities; Resonance; Vibration; dynamic response; Spectral Iterative Method; Modal analysis; Static and dynamic transmission error; Gear mesh stiffness; Macro and micro-geometry; Phasing;

   Abstract : Due to their large torque-speed ratio and transmission efficiency, planetary gears are widely used in the automotive industry. However, high amplitude vibrations remain their critical weakness, which limits their usage especially when new strict noise legislations come into action. READ MORE

3. 7. Impact loads on the self-elevating unit during jacking operation

   University essay from

   Author : Viktor Daun; Fredrik Olsson; [2019-07-03T13:28:32Z 2019-07-03T13:28:32Z 2014]
   Keywords : Farkostteknik; Vehicle Engineering;

   Abstract : The renewable energy resource of offshore wind is believed to have a great potential in playing an essential role on the future energy market in Europe, but there are complications such as harsh weather and low accessibility. To manage this, most offshore wind turbines of today are installed and maintained using self-elevating units (SEUs). READ MORE

4. 8. Investigation of open-Source CFD software on shipyards - Analysis of combustion outlets on large yachts using openFoam®

   University essay from

   Author : Carl Jascha Mordhorst; [2019-07-03T12:39:50Z 2019-07-03T12:39:50Z 2011]
   Keywords : Transport; Farkostteknik; Transport; Vehicle Engineering;

   Abstract : Abstract Modern engineering requires detailed knowledge of forces, flow directions and velocities, when designing the vehicles of the future. In the ship building industry this is traditionally done in towing tank and wind tunnel experiments or by the long experience of skilled engineers. READ MORE

5. 9. Simulation Study on Lifted Hydrogen and Methane Jet Flames in Hot Vitiated Coflow

   University essay from

   Author : Henrik Forsting; [2019-07-03T14:52:28Z 2019-07-03T14:52:28Z 2017]
   Keywords : Farkostteknik; Hållbar utveckling; Energiteknik; Energi; Vehicle Engineering; Sustainable Development; Energy Engineering; Energy;

   Abstract : Combustion of fossil fuels is the most important energy source today. Burning fossil fuel is however expensive and bad for the enviroment. Improving the combustion technology to reduce fuel consumption, and to be able to burn renewable fuels is therefore of great importance. READ MORE

6. 10. Modelling of Whiplash Trauma Parametric study of rear-end impacts using FEM and CFD

   University essay from

   Author : Andreu Oliver González; Mourya Vanama; [2019-07-03T12:20:01Z 2019-07-03T12:20:01Z 2010]
   Keywords : Farkostteknik; Strömningsmekanik; Vehicle Engineering; Fluid mechanics;

   Abstract : This work is a combination of Finite Element (FE) modelling and Computational Fluid Dynamics (CFD) to investigate the effect of acceleration pulses, head restraint and seating posture on facet joint loads and pressure transient magnitudes on the neck injury outcome during whiplash motion. A parametric study is carried out with the FE human body model THUMS (Total HUman Model for Safety) for a variety of crash pulses and crash conditions that have a known relative risk of long term neck injuries in rear-end impacts.
