Development of Rubber Boot For Propeller Shaft 2007-01-0116
Propeller shaft boot is used under high temperature and high speed spinning operating conditions. Centrifugal force is an essential factor to be taken into consideration for designing such a boot which undergoes the said operating conditions.
There is a failure mode related to the said operating conditions where the boot bellows get to balloon in a certain amount of operating time and rupture eventually. This is related to creep property, which is one of the material characteristics of rubber boot. In order to predict the boot deformation under high temperature and high speed spin conditions, we carried out static large deformation and nonlinear analysis with centrifugal force taken into consideration, using viscoelastic model for materializing the said creep property under high temperature conditions.
As a result of our investigation, we established an evaluation method of FEA, which enables us to accurately predict boot deformation under high temperature and high speed spinning operating conditions.
This paper presents simulation of our new FEA method and boot profile for propeller shaft designed for high temperature and high speed spin operating conditions.
