  1. 11. On Modeling and Control of Flexible Manipulators

    Författare :Stig Moberg; Svante Gunnarsson; Anders Robertsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; multivariable systems; differential-algebraic equations; robots; manipulators; flexible structures; robustness; position control; nonlinear systems; closed-loop identification; frequency-response methods; industrial robots; robotics; control; feedforward; flexible arms; Automatic control; Reglerteknik;

    Sammanfattning : Industrial robot manipulators are general-purpose machines used for industrial automation in order to increase productivity, flexibility, and quality. Other reasons for using industrial robots are cost saving, and elimination of heavy and health-hazardous work. LÄS MER

  3. 12. Computational Solid Wave Propagation Numerical Techniques and Industrial Applications

    Författare :Torbjörn Ekevid; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wave propagation; multigrid; adaptivity; parallel; FEM; iterative; SBFEM;

    Sammanfattning : For wave propagation and many other physical phenomena, the dynamic effects are vital. In industrial applications, such problems are very complex and generally have to be treated by means of numerical methods. LÄS MER

  4. 13. Continuum modelling of the mechanical response of paper-based materials

    Författare :Eric Borgqvist; Hållfasthetslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paperboard; constitutive modeling; anistropy; finte deformations; plasticity; damage; continuum mechanics;

    Sammanfattning : Continuum based elasto-plastic-damage models for paperboard have been established in this work. The thesis begins with an introductory section that describes the mechanical properties of paperboard and some of the converting processes during forming of a package. LÄS MER

  5. 14. Runge-Kutta Solution of Initial Value Problems: Methods, Algorithms and Implementation

    Författare :Hans Olsson; Institutionen för datavetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; stiffness; software; computational process; differential algebraic equations; ordinary differential equations; Runge-Kutta; initial value problems; time-stepping; system; kontroll; numerisk analys; Datalogi; control; numerical analysis; systems;

    Sammanfattning : The last decades have seen a strongly increasing use of computers for modeling larger and more complex systems. This has been made possible by a combination of increasing computer power and easy-to-use graphical modeling environments and libraries of components. LÄS MER
