A sealing performance analysis for the corner of a rotary vane seal based on ANSYS

摘要

Rotary vane actuators are widely used in load simulators, hydraulic simulation turrets, and rudder surface drives. The vane seal's performance directly determines the operating performance of rotary vane actuator. In this paper, a kind of composite rotary vane seals consisted of a rubber part and a polytetrafluoroethylene part is introduced. The sealing performance of a composite seal under I2MPa hydraulic pressure, including contact pressure and leakage evaluation, is analyzed based on ANSYS software. The results shows that the corner of the PTFE part has a worse performance compared with other parts of the composite vane seals.
