Experimental Investigation of Magnetic Fluid used in Tandem mode for Underwater Vehicle System
While designing actuator such as motor and manipulator in underwater robotic vehicle (URVs) system the sealing mechanism is very prerequisite in order to prevent any leakage of sea or fresh water from coming into the robot vehicle system.Conventional sealing system such as mechanical seal,orings,rubber boots,Grafoil wedges,PTFE or v-rings are subject to frequent part changes due to leakage and short life cycle of aging effect.Replacing rubber or any ceramic components with magnetic fluid,more secure sealing effect can be acquired and thus longer life cycle time can be extended to semi-permanent scale.To maximize the sealing effect,some basic investigation such as designing a tandem mode and applying air pressure in the compartment according to the underwater depth to prevent any deterioration of magnetic fluid and minimize the effect of exert force on the magnetic fluid.Some fundamental simulation are performed using finite element method,verified by benchscale experiment and thus show a good potential if used in actual underwater robotic vehicle.
