Aiming at the failure problem of composite sealing ring, the influence of elastic modulus of carbon fiber content, groove width and number of grooves on dynamic sealing characteristics of sealing ring was analyzed by finite element method. The results showed that the maximum stress after precompression was located in the middle of the contact between slip ring and O ring, and the maximum contact pressure was located to the left of the inner circle of slip ring. After applying the fluid pressure, the maximum stress is located at the right side of the contact between the slip ring and O ring and the middle part of the contact between the slip ring and O ring, and the maximum contact pressure is located at the middle part of the inner circle of the slip ring. In dynamic sealing state, the magnitude and position of the maximum contact pressure and the maximum stress of left and right stroke are basically the same; The width and number of grooves increase the contact pressure and stress, but the width of groove interval is opposite.
