  2. 1. Response of cable-stayed and suspension bridges to moving vehicles : Analysis methods and practical modeling techniques

    Author : Raid Karoumi; KTH; []
    Keywords : cable-stayed bridge; suspension bridge; Great Belt suspension bridge; bridge moving loads; traffic-induced vibrations bridge-vehicle interaction; dynamic analysis; cable element; finite element analysis; finite diffrence method; tuned mass damper; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This thesis presents a state-of-the-art-review and twodifferent approaches for solving the moving load problem ofcable-stayed and suspension bridges. The first approach uses a simplified analysis method tostudy the dynamic response of simple cable-stayed bridgemodels. READ MORE

  4. 2. Human Postures and Movements analysed through Constrained Optimization

    Author : Robert Pettersson; Anders Eriksson; Elena Gutierrez-Farewik; Hans Berg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multibody system; optimal control; trajectory optimization; long jump; posture; Other engineering mechanics; Övrig teknisk mekanik;

    Abstract : Constrained optimization is used to derive human postures and movements. In the first study a static 3D model with 30 muscle groups is used to analyse postures. The activation levels of these muscles are minimized in order to represent the individual's choice of posture. READ MORE

  5. 3. Towards Optimization of Railway Turnouts

    Author : Björn Pålsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamic vehicle–track interaction; turnout; switch crossing; wheel and rail wear;

    Abstract : The turnout (Switch & Crossing) is a vital component in railway networks as it provides flexibility to traffic operation by allowing trains to switch between tracks. The flexibility comes at a cost as the common lack of a transition curve in the diverging route together with the variation and discontinuities in rail profiles result in higher rail degradation rates than in regular track.
