  1. 26. A methodology for situated and effective design of haptic devices

    Författare :Xuan Sun; Kjell Andersson; Ulf Sellgren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design optimization; haptic devices; metamodel; multi-criteria; situatedness; Machine Design; Maskinkonstruktion;

    Sammanfattning : The realism of virtual surgery through a surgical simulator depends largely on the precision and reliability of the haptic device. The quality of perception depends on the design of the haptic device, which presents a complex design task due to the multi-criteria and conflicting character of the functional and performance requirements.

  3. 27. Synchronous Machines with High-Frequency Brushless Excitation for Vehicle Applications

    Författare :Junfei Tang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrically Excited Synchronous Machines; Machine Modeling; Brushless Excitation; Machine Control; Machine Design; Electric Vehicles;

    Sammanfattning : Electrically excited synchronous machines (EESM) are becoming an alternative to permanent magnet synchronous machines (PMSM) in electric vehicle (EV) applications. This mainly attributes to the zero usage of rare-earth material as well as the capabilities of high starting torque and good field weakening provided by EESM. LÄS MER

  4. 28. Cultivating Mechanical Sympathy : Making meaning with ambiguous machines

    Författare :Joseph La Delfa; Kristina Höök; William Odom; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drones; Aesthetics; Design; Human-Computer Interaction; Human-Drone Interaction; Human-Robot Interaction; drönare; estetik; design; människa-datorinteraktion; människa-drönarinteraktion; människa-robotinteraktion; Människa-datorinteraktion; Human-computer Interaction;

    Sammanfattning : Moving with a drone can be a captivating and reflective experience. A drone can easily grab my attention, yet its hold is distinctly different to a screen where my body goes missing and my eyes are held captive. Instead, my body feels alive and present. As if every part of it is playing a crucial role in keeping the drone in the air. LÄS MER

  5. 29. Dynamic Performance and Design Aspects of Compliant Fluid Film Bearings

    Författare :Matthew Cha; Sergei Glavatskih; Kyung-Woong Kim; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compliant bearing; dynamic performance; design aspects; Machine Design; Maskinkonstruktion;

    Sammanfattning : Due to government regulations together with health and safety reasons, there are increasing demands on reducing hazardous polluting chemicals from fossil fuel power plants. Therefore, more efforts are imposed on using renewable resources such as water, wind, solar and tide to produce clean/green electricity. LÄS MER

  7. 30. 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
