1. 1. Development of a 3D Ring Dynamics Model For a Heavy-Duty Piston Ring-Pack

   Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Författare :Parthasri Akurati; Karan Kumar; [2021]
   Nyckelord :3D ring model; Flank wear; Oil consumption; Piston ring dynamics;

   Sammanfattning : With the increasing restrictions in emission legislations, the automotive industry aims to improve the efficiency of the lubricating system and to decrease fuel consumption. In the power cylinder unit (PCU), the piston rings are the major contributor to these consumptions. LÄS MER

3. 2. Determining the viscous splash losses in the housing of a hydraulic motor through CFD-simulations : A master thesis in collaboration with Bosch-Rexroth in Mellansel AB

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Författare :Tommy Larsson; [2017]
   Nyckelord :CFD computational fluid dynamics splash losses efficiency;

   Sammanfattning : One possible way of solving future energy shortages is by the optimization of our current energy consumption. These optimizations must span all possible fields of consumption. In the mechanical field radial piston hydraulic motors may show some margin of improvement. LÄS MER
