1. 11. Non-Linear Characteristics of a Pendulum System

   University essay from Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Author : Wei Zongyuan; Pir Aamir Ali Shah; V.K.C Varma Rudraraju; [2010]
   Keywords : Nonlinearity; Coupled SDOF-pendulum system; Distortion; Simulation; Frequency Response Function. ;

   Abstract : In this master thesis, the dynamics of a moving point pendulum and coupled pendulum system are analyzed. First the time simulation is performed. The periodic and non-periodic states of the system are analyzed with varying fundamental forcing frequencies and amplitudes. The amount of distortion in the response is studied. READ MORE

   Keywords : Submerged body; Dynamic characteristic; Hydrostatic stiffness; Added mass and damping; Modal test; COMSOL Multiphysics; SDOF;

   Abstract : Modeling the dynamic of a submerged body has received a wide attention in the recent years. The trend is toward modeling the buoyancy and motion of the sub- merged body considering di®erent variables affects on it. READ MORE

4. 13. Dynamic Behaviour of Footbridges Subjected to Pedestrian-Induced Vibrations Studies

   University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Väg- och vattenbyggnad (CI)

   Author : Fjalar Hauksson; [2005]
   Keywords : Technology and Engineering;

   Abstract : Over the last years, the trend in footbridge design has been towards greater spans and increased flexibility and lightness. As a consequence, stiffness and mass have decreased which has lead to smaller natural frequencies and more sensitivity to dynamic loads. READ MORE
