  2. 6. Active Vibration Control of Multibody Systems : Application to Automotive Design

    Author : Claes Olsson; Alexander Medvedev; Stephen Elliott; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Vibration Control; Vibration Isolation; Feedback Control; Adaptive Filtering; Saturation; Limit Cycles; Multi Body Systems; Modelling; Simulation; Non-linearity; Gain Scheduling; Structure Flexibility; Automatic control; Reglerteknik;

    Abstract : Active vibration control to reduce vibrations and structure borne noise is considered using a powerful multi-disciplinary virtual design environment which enables control system design to be considered as an integral part of the overall vehicle design. The main application studied is active automotive engine vibration isolation where, first, the potential of large frequency band multi-input multi-output H2 feedback control is considered. READ MORE

    Abstract : New combustion engine principles increase the demands on feedback combustion control, at the same time economical considerations currently enforce the usage of low-end control hardware limiting implementation possibilities. Significant development is simultaneously and continuously carried out within the field of Field Programmable Gate Arrays (FPGAs). READ MORE

  5. 8. Developing Methods for Modelling Procedures in System Analysis and System Dynamics

    Author : Hördur Haraldsson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System Dynamics; System Analysis; group model building; modelling procedures; innovation phases; modelling workflow; Natural science; Naturvetenskap; Technological sciences; Teknik;

    Abstract : System Thinking is the mindset of defining and confining a problem and its symptoms as well as a method for communicating system understanding. System Analysis is taking that problem apart to understand its causalities and structural arrangement. READ MORE

  6. 9. Methods for efficient modelling of progressive failure in laminated fibre-reinforced composites

    Author : Johannes Främby; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Composites; Progressive failure; Crash simulation; Adaptive modelling;

    Abstract : To meet increasing demands on reduced CO2 emissions, the automotive industry is currently very active in research to reduce vehicle weight by incorporating laminated composites (primarily carbon fibre-reinforced polymers) into structural components. Historically, composite materials have mainly been used in the aerospace industry, whereby CAE-based design and development tools for composite structures have been developed primarily to the specific needs and requirements in this industry.

  7. 10. Modelling the Structural Dynamics of Business Networks : Two Agent-based Models of Supply Networks

    Author : Sara Shahin Moghadam; Frans Prenkert; Franziska Klügl; Magnus Hansson; Davide Secchi; Örebro universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business networks; dynamics; Agent-based modelling; structural change; responses; interactions; complex adaptive systems;

    Abstract : This thesis aims at describing and analysing the structural changes of business networks that emerge as a result of change triggers. Despite previous studies, our understanding of the evolution of the network structure and its influencing factors is still limited. READ MORE
