摘　　要：针对新型电缆密封结构的密封挡板、密封结构板、橡胶密封板及其连接螺栓建立了有限元模型,考虑了几何、边界及材料非线性因素,计算了模型在螺栓预紧力和气压作用下电缆密封结构的应力和变形,校核该结构的强度是否满足设计要求。结果表明,密封结构的局部出现屈服,需更换更高强度的材料;密封结构密封性能良好,密封性能试验验证了计算结果的合理性。Aimed at a new type of cable seal structure,the finite element model of sealing buffle plate,sealing plate,rubber plate and bolt were established.Considering the geometric nonlinear,boundary nonlinear and material nonlinear,the stress and strain of the structure under the action of pressure and bolt load were calculated.Moreover,the stiffness of the structure was investigated in the paper.The results show that the local stiffness of cable seal struc-ture is yield and the material should be changed;Moreover,the sealing of the structure is finer,which is proved rea-sonable by the sealing experiment.
