The hydroelastic analysis of marine propellers with consideration of the effect of the shaft
چکیده انگلیسی
At present, most studies on the hydroelastic analysis of marine propellers do not consider the effect of the shaft. So in this paper, with consideration of the effect of the shaft and bearings, a fluid-structure interaction model of the marine propeller is established by coupled boundary element method (BEM) and finite element method (FEM). The hydroelastic performance of the propeller is discussed with and without consideration of the shaft and bearings. The research shows that the natural frequencies of the blade attached at the shaft are slightly less than those without shaft. This would be more prominent as the shaft's flexibility is increased. There are some errors for the hydroelastic performance of propellers if the shaft and bearings are ignored. So the shaft should not be neglected in the prediction of the propellers' hydroelastic performance.
