摘　　要：针对储气罐的橡胶密封结构,分别建立了单层和层形橡胶密封膜的有限元模型,利用有限元软件Ansys对比分析单层橡胶密封膜在不同长度和厚度下的密封性能,并与其优化结构参数的添加增强层的层形橡胶密封膜进行比较。结果表明:随着厚度的增大,单层橡胶密封膜的最大形变量和等效应力峰值整体上均先减小后趋于平缓;大工况压强下采用添加增强层的层形橡胶密封膜的密封性能优于单层橡胶密封膜,层形橡胶密封膜具有较小的最大形变量和等效应力峰值以及较大的安全因数最小值,有利于提高橡胶密封膜的密封性能和延长其使用寿命。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.
