  1. 16. Thermomechanical stress analysis of the main insulation system of traction electrical machines

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Dahman Ismail; Alexis Andrei; [2020]
    Keywords : finite element analysis; thermo-mechanical stress; heavy-duty vehicle; electrical machine; insulation system; coupled-temperature displacement analysis; finita element analys; termomekaniska spänningar; lastbilar; elektriska motorer; isolering; termisk kopplingsförbindelse;

    Abstract : More efficiency heavy-duty vehicles are developed with higher range, updated electronic and mechanical parts. The fuel efficiency and pollution of carbon dioxide need to be lower to achieve new EU regulations. The global population increases with an increased number of heavy-duty vehicles. This, in turn, increases the emission. READ MORE

  3. 17. Analysis of wall-mounted hot-wire probes

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Alvisi Alex; Perez Adalberto; [2020]
    Keywords : Turbulent Boundary layer; Turbulent Channel Flow; Hot Wire Anemometer; Direct Numerical Simulations; Immersed Boundary Method;

    Abstract : Flush-mounted cavity hot-wire probes have been around since two decades, but have typically not been applied as often compared to the traditional wall hot-wires mounted several wire diameters above the surface. While the latter suffer from heat conduction from the hot wire to the substrate in particular when used in air flows, the former is belived to significantly enhance the frequency response of the sensor.

  4. 18. An armored truck cab design : Case study: investigation of selected steel grades

    University essay from KTH/Materialvetenskap

    Author : Filippo Pellegrini; [2020]
    Keywords : Ballistic steel; single and double layer protection; truck cab; dynamic softening; Ballistiskt stål; enkel- och dubbelskiktsskydd; konstruktion av lastbilshytt; dynamisk mjukning;

    Abstract : This study aimed at defining useful guidelines for the design of an armored truck cab. Particularly, the quality and performance of ballistic steel were defined, considering not too high demanding requirements. Two steel grades, corresponding to hardness of 500 HB and 600 HB, and three different suppliers were selected. READ MORE

  5. 19. Design of multilayer paperboard for optimisedcompression strength

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Ali Salem Ali; [2020]
    Keywords : Compression strength; Paper; Cardboard; Dynamique Formette; Dynamic sheet former; SCT; Shortspan compression test; fibre; fibre properties; fiber; fiber properties; Multilayer;

    Abstract : This master thesis was issued by BillerudKorsnäs Gruvön. The focus of this thesis was theinvestigation of the effects different fibre types has on the compression strength of the whole paper product. This stems from wanting to better understand how to produce a better paperboard construction with respect to stacking, storage, and transport. READ MORE
