Download or read book Propeller Vibration and Stress Analysis by Finite Element Methods PVAST Version 4 written by and published by . This book was released on 1992 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: PVAST is a computer program for the strength & vibration analysis of marine propellers. It is based on the finite element method of structural analysis and is designed to automatically generate finite element models from a large library of elements for a wide variety of propeller geometries. The program can graphically display the model & the propeller geometry and can carry out static, natural frequency, & dynamic response analyses as well as display the analysis results in graphic form. This user manual includes descriptions of the finite element method, equations, & solving schemes used in PVAST analyses; the finite elements offered for propeller modelling and the modelling options available in the program; program organization & operation; features & usage of the program for pre- & post-processing; and how to use PVAST effectively & efficiently. Appendices include additional information on input data, load generation, plotting, generation of models for the fluid surrounding the blade, blade geometry generation, the geometry of marine propellers, and generation of air channel models.

Available in PDF, EPUB and Kindle. Book excerpt: Static stresses were obtained in laboratory experiments for a destroyer propeller, having aerofoil blade sections, and a super-cavitating propeller, having wedge-shaped blade sections, using specially constructed pressure chambers that allowed the blade faces to be loaded under air pressure. A new method for applying beam theory is presented that closely predicts the magnitude and distribution of radial stresses on the destroyer propeller blade. For the supercavitating propeller, neither the proposed beam-theory method nor a particular computerized-shell analysis can be considered entirely satisfactory for prediction of blade stresses.

Download or read book Stress Analysis of Rotating Propellers Subject to Forced Excitations written by and published by . This book was released on 2015 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Turbine blades experience vibrations due to the flow disturbances. These vibrations are the leading cause for fatigue failure in turbine blades. This thesis presents the finite element analysis methods to estimate the maximum vibrational stresses of rotating structures under forced excitation. The presentation included starts with the derived equations of motion for vibration of rotating beams using energy methods under the Euler Bernoulli beam assumptions. The nonlinear large displacement formulation captures the centrifugal stiffening and gyroscopic effects. The weak form of the equations and their finite element discretization are shown. The methods implemented were used for normal modes analyses and forced vibration analyses of rotating beam structures. The prediction of peak stresses under simultaneous multi-mode excitation show that the maximum vibrational stresses estimated using the linear superposition of the stresses can greatly overestimate the stresses if the phase information due to damping (physical and gyroscopic effects) are neglected. The last section of this thesis also presents the results of a practical study that involves finite element analysis and redesign of a composite propeller.
