  1. 1. Rotor Dynamic Modeling of Hydropower Rotors by 3D-Finite Element Analysis

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Simon Pääjärvi; [2022]
    Keywords : Rotordynamics; Applied Mechanics; Dynamics; Rotor; Finite Element Analysis; Hydropower; Solid Mechanics; Energy Production;

    Abstract : By using the rotor dynamic capabilities of Simcenter Nastran Rotordynamics, an eigenvalue analysis of 3D-finite element models of the Jeffcott rotor and the overhung rotor were conducted and compared to the results with beam-based, lumped parameter models. The first two critical speeds of the Jeffcott rotor were estimated with variations of 3. READ MORE

  3. 2. Investigation of the behaviour of return collectors on Paris’ subway MP05 (Line 1)

    University essay from KTH/Järnvägsteknik

    Author : Theo Le Bars; [2014]
    Keywords : Rubber-tyred subways; return collector; rigid solid mechanics; contact.;

    Abstract : Return collectors are predominant organs for rubber-tyred subways to operatesince they ensure both the track circuit shunt and the traction current return. Po- sitioned at the interface between the track and the rolling stock, they are subjected to the disruptions linked to the train movement and the track irregularities. READ MORE

  4. 3. An Algorithm for Structural Topology Optimization of Multibody Systems

    University essay from Lunds universitet/Matematik LTH

    Author : Toheed Ghandriz; [2014]
    Keywords : Dymola; Abaqus; TOSCA; nonlinear Differential Algebraic Equation; finite element method; flexible body; SIMP; dynamic body; Topology Optimization of Multibody Systems; flying element; Technology and Engineering;

    Abstract : Topology Optimization (TO) of static structures with fixed loading is a very interesting topic in structural mechanics that has found many applications in industrial design tasks. The extension of the theory to dynamic loading for designing a Multibody System (MBS) with bodies which are lighter and stronger can be of high interest. READ MORE

  5. 4. Breaking of a rod induced by wave propagation.

    University essay from KTH/Teoretisk fysik

    Author : Erik Zhang; [2014]
    Keywords : ;

    Abstract : The aim of this project is to visualize multiple failure of an inelastic rod, caused by wave propagating through the rod, as the result can be applied to a spaghetti where it commonly breaks into multiple pieces. By looking into the wave we will see that when the wave propagates, it will cause local increase of bending which causes a secondary break. READ MORE
