  1. 6. Model-based design of haptic devices

    Författare :Ahmad Aftab; Kjell Andersson; Ulf Sellgren; Per Wennhage; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Haptic device; model-based design; stiffness; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : Efficient engineering design and development of high precision and reliable surgical simulators, like haptic devices for surgical training benefits from model-based and simulation driven design. The complexity of the design space, multi-domains, multicriteria requirements and multi-physics character of the behavior of such a product ask for a model based systematic approach for creating and validating compact and computationally efficient simulation models to be used for the design process.

  3. 7. On Aircraft Conceptual Design : A Framework for Knowledge Based Engineering and Design Optimization

    Författare :Kristian Amadori; Petter Krus; Christopher Jouannet; Johan Ölvander; Ulf Sellgren; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer and systems science; Data- och systemvetenskap;

    Sammanfattning : This thesis presents a design framework where analytical tools are linked together and operated from an efficient system level interface. The application field is aircraft conceptual design. Particular attention has been paid to CAD system integration and design optimization.Aircraft design is an inherently multidisciplinary process.

  5. 9. On synchronization of heavy truck transmissions

    Författare :Daniel Häggström; Ulf Sellgren; Stefan Björklund; Anders Hedman; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; synchronization; synchronizers; gear shift; gearbox; synkronisering; växling; växellåda; Machine Design; Maskinkonstruktion;

    Sammanfattning : Gear shifts are becoming more and more important as engines are adapted to low speed high torque working conditions. Synchronizers are key components for successful gear shifts. To adapt the synchronizers to new working conditions due to adaptations to new engines, improved development tools are needed. LÄS MER

  7. 10. Towards model-based development of heavy truck synchronizers

    Författare :Daniel Häggström; Ulf Sellgren; Pär Marklund; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; synchronization; synchronizers; gear shift; gearbox;

    Sammanfattning : Gear shifts are becoming more and more important as engines are adapted to low speed and high torque working conditions. Synchronizers are key components for successful gear shifts. To adapt the synchronizers to future engines and thus new working conditions, improved development tools are needed. LÄS MER
