Other AbstractUnder the effects of seawater temperature, salinity and depth, the buoyancy of AUV would change when it implements deepwater operations, leading to many navigation performance problems. To tackle these problems, buoyancy regulating devices have been developed, which are of significance for the development of long - voyage and high -submergence AUVs. In this paper, a piston cylinder buoyancy regulating device is designed, which utilizes the hydraulic system to drive the fluid cylinder to absorb and discharge seawater, so as to achieve buoyancy adjustment. Linear displacement sensors are adopted to measure the amount of oil variation, thus calculating the value of buoyancy regulation in an indirect way. Then the hydraulic system is simulated on the platform of AMESim, and the dynamic characteristics of the hydraulic cylinder are analyzed, which provides the theoretical guidance for the testing of a practical system. Finally, the Hydraulic Component Design (HCD) library is utilized to establish models for analysis and comparison, so as to verify the equivalence of hydraulic library modeling and HCD modeling.
