Wind resource assessment in cold climate regions

Jin, Jiayi (Master thesis; Mastergradsoppgave, 2017-06-14)

Cold regions have good potential for wind energy development, but icing on wind turbines is recognize as a hindrance limiting the wind energy production in ice prone cold regions. This master thesis work is linked with Wind-CoE project of Arctic Technology Research Team and is aimed on better understanding of wind resource assessment in cold regions. Three years (2013-15) field SCADA data from ...

Research on optimization of freeform surface operation

Liu, Dingjun (Master thesis; Mastergradsoppgave, 2017-06-14)

Nowadays, many manufacturing companies need to face competition both in domestic and international level. Due to this circumstance, manufacturers recognize that one useful method to enhance their competence is reducing the lead-time of manufacturing. There are many researchers focused on minimize the time of actual cutting, tool path optimization and energy consumption optimization etc. However, few ...

Heavy multi-pass TIG welding

Maske, Tomas (Master thesis; Mastergradsoppgave, 2017-05-23)

This study aims to find the maximum, usable, feed limit at different arc-energies and use the findings in multi-pass welding planning for robotic welding, taking into consideration the high controllability of robot movements. A combined studies using numerical analyses and practical experiments to calculate the feed limits for different arc energies. Each weld where analysed both mathematical, ...
