    Author : Johan Pilthammar; Sharon Kao-Walter; Mats Sigvant; Wolfram Volk; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sheet Metal Forming; Stamping Die; Virtual Tryout; Digital Twin; Stamping Press; Structural Analysis; Finite Element Simulation; Optimization; Digital Image Correlation; Inverse Modeling; Maskinteknik; Mechanical Engineering;

    Abstract : Competition and complexity in the global car market are continuously increasing. To gain an edge in the market while making a profit, each competitor in the market needs a strong focus on technology development. Such a focus will increase the value of the product for the customers. READ MORE

  4. 12. Ergonomics Methods and Work Procedures in Car Manufacturing for Improvement of Quality, Productivity and Health at Work

    Author : Ann-Christine Falck; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cost-benefit; ergonomics; manufacturing; productivity; risk assessment; quality;

    Abstract : Many studies have concluded that there are great human and economic gains in finding ergonomically sound solutions as early as possible in product and production development. Hence, the objective of the research presented in this thesis was to evaluate methods for improved ergonomics assessment in early phases of product and production development and in production.

  5. 13. A Simulation-Based Optimisation Method for PLC Systems

    Author : Bo Svensson; Bengt Lennartson; Rolf Bernhardt; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulation based optimisation; Virtual manufacturing; Industrial control system; PLC; Continuous simulation; Parameter tuning; Optimisation methods; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Tuning of process parameters such as time constants, cam values, velocities and robot paths, in order to increase capacity utilisation, is today a challenging manual on-line task in many automated manufacturing systems. On-line methods interfere with production and will cause unwanted downtime, which indeed reduces capacity utilisation. READ MORE

  6. 14. Virtual reality in construction : tools, methods and processes

    Author : Stefan Woksepp; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction Engineering and Management; Byggproduktion;

    Abstract : Present-day construction projects are characterized by short-term partnerships between multidisciplinary teams with varying levels of process maturity and information handling capability. They involve the planning, design and erection of structures of all types. READ MORE

  7. 15. On Virtual Development of Manufacturing Systems -Proposal for a Modular Discrete Event Simulation Methodology

    Author : Björn Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Productivity Development; Knowledge; Manufacturing Systems; Discrete Event Simulation;

    Abstract : This thesis formulates one approach on how to reuse and take advantage of knowledge and data for discrete event simulation of manufacturing systems. The approach uses modularity and division of knowledge in order to present a methodology for modular discrete event simulation. READ MORE
