Abstract: The finite element analysis model of rubber Y-Sealing ring is established by the finite element software. Installation mode of stress and strain distribution of the seal ring is analyzed. Analyses the stress and strain of Y-Sealing ring under different loads and different compression ratios. The stress and strain under different compression ratios and loads are calculated by finite element software. The regularity of seal between compression ratio and load is obtained by the analysis and contrast to different stresses and strain contours. The optimization analysis was carried out on Y-Sealing ring for the purpose of avoiding the lower lip is packed into the clearance. The sealing structure finite element analysis can do certain theoretical reference value to the design and installation of the seals.
