1. 1. CHARACTERISATION OF CROSS LAMINATED TIMBER PROPERTIES

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

   Författare :Emil Nilsson; [2021]
   Nyckelord :CLT; cross laminated timber; in-plane loading; out-of-plane loading; beam; rolling shear modulus; experimental tests; FE-modelling; Technology and Engineering;

   Sammanfattning : This project concerns an analysis of a hitherto untested method for determining the modulus of elasticity (MoE) and shear modulus parallel to grain, as well as the rolling shear modulus of cross laminated timber (CLT) through 3-point bending tests. A review of analytical models and methods is included, followed by an evaluation of the effect of the annual ring orientation and shear stress distribution at shear loading of individual board cross-sections.

3. 2. SUSTAINABLE LUBRICATION FOR FUTURE TRANSMISSIONS : Micropitting performance of Glycerol-based lubricants

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Zapata Tamayo Juan Guillermo; [2021]
   Nyckelord :micropitting; mild sliding wear; surface coating; diamond-like carbon DLC; glycerol-based lubrication; green lubricant; rolling contact fatigue; rolling-sliding;

   Sammanfattning : Achieving sustainable lubrication by using environmentally friendly formulated lubricants has became an essential component of the transition process from fossil-powered vehicles to electrified transportation. Mixtures, or aqueous solutions of molecules such as polyhydroxy alcohols, and glycols usually known as green lubricants make it possible to achieve low friction coefficients under different lubrication conditions, which constitutes a potential alternative to improve the tribological performance of moving parts in automotive systems, at the same time that the environmental requirements are satisfied.

4. 3. Mechanical modelling of gaskets in exhaust after-treatment system of trucks

   Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

   Författare :Aneesh Ravikumar; [2020]
   Nyckelord :;

   Sammanfattning : With the world proceeding towards a clean and sustainable environment,the creation of technology and its implementation also needs to be sustain-able. The importance of combustion engine vehicles to meet more stringentemission standards puts a requirement on the industry to develop suitableafter-treatment systems to meet those standards. LÄS MER

5. 4. Optimization of diagonal stiffeners to handle wind pressures on silos

   Master-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

   Författare :Max Hellberg; [2019]
   Nyckelord :;

   Sammanfattning : In this report the focus is set on how to optimize the support structure of a silo and in particular, the stiffeners and fastener. The main force of the silo comes from the wind pressures. The design is subjected to the Swedish and European standards SS-EN 199-1-4:2005, 1993-1-1:2005 and 1990. LÄS MER

7. 5. Drag Torque and Synchronization Modelling in a Dual Clutch Transmission

   Master-uppsats, Lunds universitet/Maskinelement

   Författare :Mikael Lund; [2018]
   Nyckelord :drag torque; synchronization; dual clutch transmission; Technology and Engineering;

   Sammanfattning : Noise, vibration and harshness (NVH) is a big consideration in the automotive industry. In order to create an as pleasant driving experience as possible for the driver, NVH should be minimized. One of the sources of NVH comes from the transmission due to the synchronization process.
