Abstract:
      The finite element models of the single layer and multi-layered rubber sealing films were established for the rubber sealing structure of the gas storage tank，respectively.The sealing performances of the single layer rubber sealing films with different lengths and thicknesses were analyzed by using the finite element software Ansys，and compared with themulti-layered rubber sealing film with the reinforcing layer and optimized structural parameters.The results showed that，with the increase of the thickness，the maximum deformation and von Mises stress peak value of the single layer rubber sealing film decreased first and then levelled off.The sealing performance of the multi-layered rubber sealing film with the reinforcing layer was better than that of the single layer rubber sealing film，particularly，under heavy-duty working pressure.Moreover，the multi-layered rubber sealing film had smaller maximum deformation and von Mises stress peak value and larger minimum value of safety coefficient，which was conducive to improving the sealing performance and extending the service life of the rubber sealing film.
