Dynamic response of an under-water fuel transfer system

This paper discusses the dynamic response of a fuel transfer system that is supposed to transport fuel rods under-water. The under-water fuel transfer system is usually utilized in the process industry and in deep sea for oil transportation from the exploration sites. In both the cases fuel transfer system is exposed to environmental disturbances which define its dynamic response and are detrimental to system´s performance. It is therefore, necessary to study the dynamic response of such a system for its desired application. This paper discusses the problem of studying the dynamic response of a fuel carrying rod that travels along a straight path from one position to another with maximum speed so that, when it reaches the desired position, there is minimal residual vibration (sway). A mathematical model is derived for the system, considering the effects of hydrodynamic forces acting on the fuel carrying rod. An experiment is also conducted to study the dynamic behavior of the rod while it travels under-water and the residual vibrations (sway) at the end point are suppressed using the input shaping technique.
