Study on Sealing Behavior of Laterally One Side Restrained C-Ring under Internal Pressure by Numerical Simulation

This paper established a 3 D numerical simulation method to study the laterally one side restrained C-ring under internal pressure. In this paper, it found that with the internal pressure forcing and sealing groove squeezing, C-ring would generate additional plastic deformation, which would decrease the sealing performance of C-ring. When p＞20 MPa, the ratio of decreasing becomes bigger. In order to guarantee the sealing reliability of C-ring, the internal pressure cannot exceed 100 MPa.
