Mathematical Modelling and Analysis of Submarine Propeller Shaft

Abstract

In this research modeling, design and analysis of a submarine propeller shaft will be performed using theories of vibrations, the computer software will be used for this purpose mathematical simulations will also be done to verify the results obtained from the software. Vibration Analysis of a three Bladed Propeller Shaft for a Carrier has been discussed in the literature, but not much work has been done till now on the vibrational response of a submarine propeller shaft. The dynamic excitation of the propeller shaft is usually transmitted to the rest of the submarine. Some submarines are subjected to intense levels of vibrations throughout their service additionally silent submarines have become a potent invention, which produces less noise at high speeds however higher vibration results in more noise-reducing the stealth characteristics of the submarines, in this research the propeller shaft will be modeled in such a way that the system vibrations are minimum hence increasing the life of the submarine, reducing the noise and increasing the stealth characteristics of the submarine, this analyses will be done by using theories of vibrations used finite element methods for modelling and analysis. The expected results from the analysis contain the least vibrations, produced by the propeller shaft of the submarine reducing the overall noise. Furthermore, their result help in the development of a system that besides increases the maneuverability of the submarine. We are able to successfully determine the vibration present in the system, and the approach on how to reduce them.
