1. 21. Finite Element Analysis and Design of Experiments in Engineering Design

   Författare :Martin Eriksson; Innovation; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite element analyses; Predictive Design Analysis; Mechanical engineering design process; Design Of Experiments; Predictive Engineering;

   Sammanfattning : Projects with the objective of introducing Finite Element Analysis (FEA) into the early phases of the design process have previously been carried out at the Department of Machine Design, see e.g. the Doctoral thesis by Burman [13]. These works clearly highlight the usefulness of introducing design analysis early in the design process. LÄS MER

   Sammanfattning : Modern product development is a complex chain of events and decisions. The ongoing digital transformation of society, increasing demands in innovative solutions puts pressure on organizations to maintain, or increase competitiveness. LÄS MER

4. 23. Dimensioning Tools of MEA Actuator Systems, Including Modeling, Analysis and Technology Comparison

   Författare :Mohsen Torabzadeh-Tari; Göran Engdahl; Hans Bernhoff; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dimensioning tools; MEA; More Electric Aircraft; EMA; Electro Mechanical Actuator; EM; Electrical Machine; Converter; Inverter; Finite Element Method; FEM; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

   Sammanfattning : Aircraft design is an example of complex engineering where dimensioning tools can be valuable for the designers and decision makers in the early stage of the development process. These tools can be in form of a database over key numbers for different components or technologies. One of the critical parts of an aircraft is the actuator system. LÄS MER

5. 24. FE-Simulation of Metal Cutting Processes

   Författare :Ahmet Semih Ertürk; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inverse identification; Machine learning; Metal cutting; Finite element method; Heat transfer; Machining;

   Sammanfattning : Machining a new component or a new material requires the selection of the cutting conditions, the tool material and the tool geometry. The selections should be also optimized for the existing components and materials to improve the quality of the produced components and reduce the cost of production. LÄS MER

7. 25. Aspects of adaptive mesh refinement in the spectral element method

   Författare :Nicolas Offermans; Philipp Schlatter; Ananias Tomboulides; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Error estimators; mesh refinement; adaptivity; spectral element method; algebraic multigrid method; NACA4412; periodic hill case.; Engineering Mechanics; Teknisk mekanik;

   Sammanfattning : This thesis deals with the improvement of the efficiency of numerical simulations in computational fluid dynamics. Some of the limitations of current algorithms on future exascale supercomputers are addressed with the main goal of using adaptive mesh refinement for the simulation of turbulent and three-dimensional flows.
