Study on Complex Dynamic Pressure Metal Seal in Rotary Vane Steering Gear Based on Fluid Structure Interaction
Cast-iron sealing devices using springs are commonly used in rotary vane steering gear. These devices have good wear resistance, long service life and maintenance-free. Finite Element Analysis of cast-iron sealing device includes contact analysis of metal materials effecting of fluid action. ADINA was used to carry on sealing mechanism of cast-iron sealing device based on taking Fluid-Structure Interaction(FSI) and contact analysis into consideration and the complex dynamic pressure metal seal with ability of automatic compensation is proposed and verified that it can enhance the sealing ability of rotary vane steering gear up to 10MPa and improve power density of steering gear which has important significance to improving controllability of ship.
