The Prediction of the Strength and Natural Frequencies of Vibration of CFAV QUEST Propellers NRC (National Research Council) 45 and NSMB (Netherlands Ship Model Basin) 5363,

Abstract

The strength and vibration characteristics of the original NRC 45 and the new NSMB 5363 propellers for CFAV QUEST are predicted using the finite element computer program PVAST. The static blade loadings for the analysis were produced with the M.I.T. Program PINV 4. Predictions are presented for stresses, static displacements, and natural frequencies of vibration for both propellers. Static stress results obtained using PVAST are shown to be in good agreement with those supplied by the Netherlands Ship Model Basin for the NSMB 5363 propellers. Keywords: Marine propellers; Strength(mechanics); Structural analysis; Research vessels; Stresses; Fluid structure interaction; (Canada).
