Numerical simulation and abrasion life calculation of X-ring for hydraulic actuators of a certain aircraft

In this paper, the X-ring for hydraulic actuators of a certain aircraft was analyzed in order to reinforce the sealing performance of hydraulic actuators, prolong the life of the sealing ring and prolong the service life of the sealing ring. The contact stress and equivalent stress under different compression are simulated by ABAQUS. The location where X-ring is prone to tear failure is found out. According to the contact stress, the wear life of X-ring is analyzed. Areas prone to wear have been found, and the wear life analysis method of X-ring is obtained. The work in this paper provides critical references for the engineering design and application of X-ring in the hydraulic actuator, and it can effectively reduce the failure rate and prolong the service life of the sealing ring. And they can be further applied in the safety analysis of airplane hydraulic actuator seal.
