1. 1. Tribological characterization of a ball bearing subjected to an electric field : Electric drivetrain tribology

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Muhammad Umar Farooq; [2023]
   Keywords : Ball bearing; electric drivetrain; tribology; electric field; characterization; bearing currents; discharge;

   Abstract : Electric machines are widely used in for instance the automotive industry in electric vehicles and in wind turbines. The electrical machines have mechanical bearings as an integral part used to transmit power and load. In addition, the main function includes reducing friction between interacting surfaces.

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

   Author : Lili Zsófia Domián; [2023]
   Keywords : Rhinocort; viscosity; rheology; thixotropy; pharmaceutical technology; Technology and Engineering;

   Abstract : The number of people suffering from the unpleasant symptoms of allergic rhinitis is increasing due to environmental and other factors. This not only makes life difficult for the individual but also places a heavy burden on society, which is why treatment is needed. READ MORE

4. 3. Evaluation of Coefficient of Friction in Oblique Helmet Impacts: An Experimental and Numerical Study

   University essay from KTH/Hållfasthetslära

   Author : Philip Singh; [2022]
   Keywords : FE model; friction; helmet impact; LS-DYNA; FE-modell; friktion; hjälmislag; LS-DYNA;

   Abstract : The focus of this thesis was to increase the knowledge in the area of "dynamic friction" during oblique helmet impacts, both experimentally and numerically. Physical experiments have been performed with multiple helmets, different angles of the anvil and different surface materials, with results of impact forces from the anvil and accelerations of the head.

   Abstract : Cascade Drives specializes in high-performance electromechanical linear actuators (EMA). The company has developed a range of linear rack and pinion actuators based on a patented load distribution technique that allows multiple pinions to interact with a single gear rack. READ MORE

6. 5. Moment-resisting connections for glulam using birch plywood : An experimental study on both mechanical and adhesive connections

   University essay from KTH/Byggnadsmaterial

   Author : Jonatan Ringaby; [2022]
   Keywords : ;

   Abstract : The aim of this study was to investigate the load-bearing capacity and stiffness of mechanical and adhesively bonded connections in timber structures with gusset plates made of birch plywood, as a preliminary study for potential future use in long-span timber structures which could reduce the environmental impact of the building sector by substituting steel with wood products in moment-resisting connections. Birch plywood was chosen for this study due to its high bending strength in comparison to plywood made of softwoods and its availability on the market. READ MORE
