Download or read book PVAST Propeller Vibration and Strength Analysis Program Version 7 3 User s Manual written by and published by . This book was released on 2001 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is a user's manual for the finite element analysis code called PVAST (Propeller Vibration And STrength) that is used for prediction of stress and vibration in marine propellers, PVAST can automatically generate propeller finite element models from basic propeller geometry defined by the orientation of two dimensional wrapped blade sections at specified radii. A number of different models can be considered and various types of structural finite element analyses can be conducted. The program provides plotting of blade geometry and visualization of predicted finite element model displacements, stresses & mode shapes. The code has been modified recently to include a Windows-based graphical user interface and the manual includes direction on using PVAST to create, modify, & display propeller blade geometry & finite element models and to display analysis results. Sample screens & outputs are included.

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.
