【摘要】 使用有限元方法研究了某特大型真空容器采用的硬法兰单橡胶密封圈的密封结构的变形，得到了密封圈和密封槽的宽度发生变化时对密封法兰的变形及密封橡胶圈压缩量的影响及规律，为密封结构的设计优化，制订简单、可靠、方便、经济、高效的加工路线提供了理论根据。更多还原

【Abstract】 The paper is emphasized on the deformation s of the sing-ring sealing structure for different position of the sealing groove, the law of the deformation and the compress value of the sealing ring widths of a certain huge vacuum vessel by using the FEM method. It results the theoretical bases for the design optimization, the formulating of the manufacturing method with simplicity, convenience, low-cost and high-efficiency of the sealing structure.更多还原
