The Analysis on the Keyless Coupling of Rudder System by Means of the Finite Element Method

Abstract

Based on actual working conditions and parameters of the rudder system, the purpose is optimizing the connection of rudder system by keyless coupling technology. Analysis on the keyless coupling of rudder system is done by the finite element method under impact loads in different directions. It can improve the performance of keyless coupling in the specific operation conditions of rudder system to be excellent. According to the test requirements of the torque and impact, the results of the completion of the finite element analysis are verified by establishing the experimental platform of keyless coupling. Experiments and analysis of the results show that the preload is formed by the hydraulic nut in the keyless coupling and the static frictions is formed between the rudder and tiller. In the meantime, it is formed between rudder and the rudder blade which can make the working state of the rudder system stable under the required torque and impact loads.
