In this technical brief, we present detailed finite element simulations of a sealing system operating in quasi-static conditions, in the framework of the real piston actuator of a landing gear braking system. Numerical results show two peaks of the contact pressure on the rod, and demonstrate that this contact pressure remains larger than that in the fluid chamber. These numerical results are qualitatively validated by scanning electron microscopy (SEM) observations of a worn sealing system. Overall, this study shows the benefits of numerical simulation in geometrical design of sealing systems targeting a given contact pressure at the rod/seal interface.
