  1. 11. An Integrated Development Approach for Monitoring and Simulation to Predict Functional Product Availability

    Författare :Björn Backe; Mats Näsström; Ove Isaksson; Ola Isaksson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Aided Design; Datorstödd maskinkonstruktion;

    Sammanfattning : For nearly two decades, business models such as Functional Products have been in focus within research and of interest in the manufacturing industry. Functional product offers consist of hardware, software, service -support systems and management of operation which, when developed in an integrated manner, together provide the customer with an agreed-upon function with a specified level of availability.

  3. 12. The need of condition monitoring to support simulations when predicting system availability of Functional Products

    Författare :Björn Backe; Per-Olof Larsson-Kråik; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : Today, competition among product manufacturers has increased and many facebeing copied and thus losing their uniqueness. To differentiate on the market,new businesses, which extend the manufacturer’s responsibility throughsupporting and guaranteeing product performance, thus offering more value-creating activities, have received increasing interest.

  4. 13. Curving performance and nonlinear dynamic behaviour of freight cars with three-piece bogies

    Författare :Ansel Berghuvud; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : This thesis considers modelling and simulation of the dynamic interaction between freight cars and railway track. The aim of the work is to study and enhance the knowledge and understanding of the nonlinear interaction for different heavy haul freight vehicle concepts of ore wagons applied at Malmbanan/Ofotbanen in northern Sweden and Norway.

  7. 15. Simulation of welding and stress relief heat treating in the development of aerospace components

    Författare :Daniel Berglund; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : It is important to control critical dimensions of aero engine components during the manufacturing process in order to maintain the quality. However, there is also a need for reduced lead-time and cost. Simulation can be a tool to achieve this. It can give information about dimension, shape, and residual stresses after each manufacturing process. LÄS MER
