1. 41. Supporting the design phase of industrialised house building using a product platform approach : A case study of a timber based post and beam building system

   Författare :Shamnath Thajudeen; Fredrik Elgh; Martin Lennartsson; Marcus Sandberg; Jönköping University; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrialised house building; Product platform; Design support; Building system; Post and beam; Glulam; Industriellt husbyggande; Produktplattformar; Designstöd; Byggsystem; Pelar-balksystem; Limträ;

   Sammanfattning : In recent years, industrialised house building has gained shares on the Swedish house building market. The market demands for industrialised house building are exceeding the available supply of housing and experiencing a substantial increase in the housing production costs. LÄS MER

3. 42. Solar cavity receiver design for a dish-Stirling system

   Nyckelord :Concentrating Solar Power; Solar receiver; Solar simulator; Uncertainty analysis; Monte Carlo ray tracing; Experimental validation; Coatings; System modeling; Structural analysis; Creep damage; Thermal stress; Cavity receiver design; Energy Technology; Energiteknik;

   Sammanfattning : The growing concern for the climate change has led to an increasing research effort in renewable energy technologies in order to achieve a more sustainable electricity production. Concentrating Solar Power (CSP) is identified as a promising technology to deal with part of the future electricity production. LÄS MER

4. 43. Development and Validation of a Numerical Tool for the Aeromechanical Design of Turbomachinery

   Författare :María Angélica Mayorca; Torsten Fransson; Damian Vogt; Eric Seinturier; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aeromechanical design; turbomachinery; numerical tool; reduced order modeling; mistuning; ROM; aero-structure coupling; CFD; FEM; methods; Mechanical energy engineering; Mekanisk energiteknik;

   Sammanfattning : In aeromechanical design one of the major rules is to operate under High Cyclic Fatigue (HCF) margins and away from flutter. The level of dynamic excitations and risk of HCF can be estimated by performing forced response analyses from blade row interaction forces or Low Engine Order (LEO) excitation mechanisms. LÄS MER

5. 44. Enhancing Aircraft Conceptual Design using Multidisciplinary Optimization

   Författare :Daniel Raymer; KTH; []
   Nyckelord :aircraft design MDO optimization fighter UAV transport;

   Sammanfattning : Research into the improvement of the Aircraft ConceptualDesign process by the application of MultidisciplinaryOptimization (MDO) is presented. Aircraft conceptual designanalysis codes were incorporated into a variety of optimizationmethods including Orthogonal Steepest Descent (full-factorialstepping search), Monte Carlo, a mutation-based EvolutionaryAlgorithm, and three variants of the Genetic Algorithm withnumerous options.

7. 45. Towards Design Automation for Additive Manufacturing : A Multidisciplinary Optimization approach

   Författare :Anton Wiberg; Johan Andersson (Ölvander); Johan Persson; Lars Pejryd; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In recent decades, the development of computer-controlled manufacturing by adding materiallayer by layer, called Additive Manufacturing (AM), has developed at a rapid pace. The technologyadds possibilities to the manufacturing of geometries that are not possible, or at leastnot economically feasible, to manufacture by more conventional manufacturing methods. LÄS MER
