2. 1. An experimental investigation of spur gear efficiency and temperature : A comparison between ground and superfinished surfaces

   Author : Martin Andersson; Ulf Olofsson; Bengt-Göran Rosén; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gears; ground; superfinished; efficiency; temperature; running-in; dip lubrication; spray lubrication; Machine Design; Maskinkonstruktion;

   Abstract : This thesis focuses on reliability when testing gear efficiency and on how gear mesh efficiency can be increased without detrimental effects on the gears. Test equipment commonly used in gear research was analysed to identify important parameters for gear efficiency testing. READ MORE

4. 2. Adhesion and Friction - a Study on Tactility

   Author : Kenneth Duvefelt; Ulf Olofsson; Emile Van Der Heide; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Adhesion; finger; friction; humidity; material; model; tactile friction; tactility; Machine Design; Maskinkonstruktion;

   Abstract : Although we are surrounded by hundreds of surfaces we can still distinguish them from each other simply by touch. The tactile information, interpreted by our brain and given by our fingers, is precise, but to put words to the sensation is very difficult — is it smooth, sticky or harsh? We do not only perceive surfaces differently, we also describe them in our own way. READ MORE

5. 3. Systems Engineering for Computing Systems at Accelerator based Research Facilities

   Author : Thilo Friedrich; Martin Törngren; Gerrit Muller; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Systems Engineering; control system; computing system; particle accelerator; research facility; Machine Design; Maskinkonstruktion;

   Abstract : Large research facilities are major research enablers for expanding fields in various natural sciences. Traditionally built for physics and astronomy, nowadays fields like life sciences, medicine, molecular sciences and material sciences have become the driving forces, especially for particle accelerator based research facilities.

6. 4. On synchronization of heavy truck transmissions

   Author : Daniel Häggström; Ulf Sellgren; Stefan Björklund; Anders Hedman; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; synchronization; synchronizers; gear shift; gearbox; synkronisering; växling; växellåda; Machine Design; Maskinkonstruktion;

   Abstract : Gear shifts are becoming more and more important as engines are adapted to low speed high torque working conditions. Synchronizers are key components for successful gear shifts. To adapt the synchronizers to new working conditions due to adaptations to new engines, improved development tools are needed. READ MORE

7. 5. Suspended forestry machines for sustainable forestry

   Author : Abbos Ismoilov; Ulf Sellgren; Kjell Andersson; Viktor Berbyuk; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Design; Maskinkonstruktion;

   Abstract : Cut-to-length (CTL) logging is a mechanized two-machine solution. The harvester processes treestems into smaller logs and a forwarder transports the logs from the logging site to a landing areaaccessible by trucks. READ MORE
