摘要: 针对C形密封环受密封内压及密封沟槽挤压作用下的密封行为进行三维数值模拟研究。通过研究可知,密封内压及沟槽挤压的共同作用使各层结构产生额外的变形,当产生塑性变形后将影响C形密封环的密封性能。通过模拟不同大小的内压作用可知,C形密封环的密封性能将随内压的增大呈衰减趋势,当内压p>20 MPa时,衰减速率加快;另外,为了保证密封可靠性,C形密封环的最大密封内压应不超过100 MPa。Abstract: 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.
