文摘

The shaft and bearings are considered for the first time in the fluid–structure interaction model of the marine propeller. The natural frequencies of the blade attached at the shaft are slightly less than those with root fixed. There are some errors for the hydroelastic performance of propellers if the shaft and bearings are ignored.
