1. 11. Fundamentals of a Methodology for Predictive Design Analysis

   Författare :Martin Eriksson; Innovation; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Predictive design analysis; Generic design analysis process model; Confidence appraisal activities; Computer-based design analysis; Engineering design; Integration;

   Sammanfattning : The rapid development of computer-based design analysis tools and methods such as the finite element method (FEM) within computational structural mechanics (CSM), computational fluid dynamics (CFD), and multi-body systems (MBS) during recent decades has fundamentally changed the way in which products are designed and developed. Among the many advantages observed in industrial practice, one can mention improved understanding of product properties and behavior, the possibility to optimize critical design parameters and to optimize parts as well as the entire product at a system level, the possibility to explore a design space during the synthesis activity, and a decrease of the need for physical testing and thus of the number of physical prototypes needed.

3. 12. On tribological design in gear tooth contacts

   Författare :Ellen Bergseth; Ulf Olofsson; Karsten Stahl; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; friction; gear contact; gear manufacturing; surface boundary layers; surface topography; wear;

   Sammanfattning : The correct tribological design will have a considerable effect on a gear’s service life and efficiency. The purpose of this thesis is to clarify the impact of variation in the gear tooth flank tribological system on the gear contact load capacity – to increase the understanding of how surface topography and lubricant interact.

5. 14. Analysis of Work Methods in Manufacturing Systems Engineering

   Författare :Jonas Nelson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; co-operation; case study; analysis; work method; systems engineering process;

   Sammanfattning : Globalisation leading to increased lead-time pressure within engineering departments put demands on efficient human work processes. The trend is towards co-located, cross-functional teams, but also towards geographically dispersed organisations, and collaboration among specialists over not only departmental boundaries, but also across company boundaries.

   Sammanfattning : Transitioning the transport sector to clean energy sources is crucial for mitigating greenhouse gas emissions and achieving carbon neutrality. A collaborative solution, combining both electric vehicles and combustion engines using renewable fuels, may prove more effective than competitive ones. LÄS MER
