Autonomous Underwater Vehicle (AUV), as an unmanned exploration equipment, is extensively employed in both military and civilian sectors, bearing significant importance for exploitation of marine resources. As a core component, an efficient and reliable propulsion system is crucial to the overall performance and operational safety of the AUV. This paper first designs the exterior of the AUV based on the operating conditions, and utilizes ANSYS FLUENT to perform hydrodynamic analysis, thereby determining navigation resistance. Subsequently, on the basis of propeller propulsion, a crank-slider mechanism is adopted to convert reciprocating motion into continuous rotation. The reciprocating push rod motor is submerged in oil, and the flexible oil bladder separates the motor from the mechanical transmission components. The deformation characteristics of the flexible bladder under different displacement conditions are simulated and analyzed using COMSOL to further validate the rationale behind the reciprocating push rod motor propelling the propeller system. Finally, the processing and assembly of the AUV prototype are completed, and relevant underwater tests are conducted.
