摘要

摘要: 研究了封隔器胶筒在自由变形阶段受初封载荷作用下内、外表面发生位移变形的特性.依据连续介质力学理论，建立自由变形阶段的有限变形数学模型，给出了胶筒在初封轴向载荷下内、外表面径向变形的过程，得到胶筒非线性变形解析解.通过数值计算，在求解出胶筒外表面自由变形解析式的基础上，进一步分析了容易被忽略的胶筒内表面非线性变形规律和相关参数变化对其密封性能的影响.该变形特性分析可适用于不同型号的封隔器胶筒，为胶筒的密封和可靠性设计提供重要理论依据.

Abstract: The displacement and deformation characteristics of the inner and outer surfaces of the packer rubber under the initial load in the free deformation stage were investigated. Based on the continuum mechanics, a finitedeformation mathematical model was established in the free deformation stage. The process of radial deformation of the inner and outer surfaces of the packer rubber under the initial axial load was given, and the analytical solution of the nonlinear deformation of the packer rubber was obtained. Through numerical calculation, based on the solution of analytical formulae for free deformation of the outer surface, the influences of the nonlinear deformation law and the relevant parameters on the sealing performance of the inner surface were further analyzed. The results of deformation characteristics can be applied to different types of packer rubbers, and provide an important theoretical basis for the sealing and reliability design of packer rubbers.
