Dynamic Analysis of a Multi-geared Rotor Shaft System
Abstract: Gear systems are the toothed members in which the main aim is to transmit power or motion between two shafts by meshing without any slip. Motion and power transmitted between the shafts are kinematically equivalent to power or motion transmitted between frictional wheels. Vibration of gear system causes unwanted noise such as gear whirling. Noise and vibration signals from machine can contain vital information about the internal processes and provide …

Evaluation of Various Numerical Methods in Large Scale FE Simulation Codes for 3D Crack Propagation
Abstract: In this paper, four different numerical methods implemented in the large scale simulation code LS-DYNA are evaluated to determine their abilities and limitations in fracture problems especially 3-d crack propagation problems. Similar formulations are implemented in the code ABAQUS as well. These methods are: Finite Element Method (FEM), Discrete Element Method (DEM), Element Free Galerkin (EFG) method and Extended Finite Element Method (XFEM). Their methodologies are briefly described and several …

Prediction of Hydro-dynamic Force Coefficients and Shedding Frequency during Vortex Shedding Behind a Stationary Cylinder
Abstract: Vibration of slender cylinders caused by the shedding of vortices at the wake, known as vortex induced vibrations (VIV) is a topic of great research interest, since the phenomenon can reduce the fatigue life of marine risers, which are subjected to complex flow conditions in ocean environment. This paper studies in detail the accuracy with which hydrodynamic forces are predicted by different turbulence models such as k–ε and k– ω-shear …
