ajst-13403	Zhou, Zhaoming; Chen, Yukun	Simulation Analysis of Sealing Performance of Rubber Core of Rotary Blowout Preventer	2023	8	.pdf	application/pdf	4711	211	56	The contact property between rubber core and drill pipe, rubber core body and iron core is defined as limited slip. Based on the Yeoh constitutive equation, the dynamic sealing model of rubber core is established in this paper, and the sealing process of rubber core during tripping and tripping is calculated and analyzed.	cache/ajst-13403.pdf	txt/ajst-13403.txt
