Analysis of Pre-Tightening Strength of Ship Tail Shaft Coupling Based on Workbench Software

Abstract:

Coupling is mostly used for the connection of two shafts, widely in ship machinery. Because the vibration and impact of propeller under alternating load, the tail shaft work conditions are harsh, pre-tightening force plays an important role in the performance of tail shaft coupling. In this paper, based on conventional coupling, achieve pre-tightening by applying pre-tightening lock bolt at the circumference of pre-tightening nut, determine the pre-tightening force according to empirical formula, analyse the pre-tightening strength by using of Workbench finite element software, get the stress distribution of related parts, to explore the effect of pre-tightening force on the stress of related parts of coupling.
