探讨一种径向密封结构可靠性量化设计方法,对如何在密封压缩量与密封可靠性之间建立一种量化关系进行了说明。与现有密封结构经验设计相比,该方法最大的优点在于建立了密封压缩量与可靠性之间的定量数学关系,尤其适用于对可靠性要求较高的航天、航空等高风险行业。 A method to quantify the reliability of radial seal structure is discussed, and how to establish a quantitative relationship between seal compression and seal reliability is discussed. Compared with the experience design of the existing seal structure, the biggest advantage of this method is that it establishes the quantitative mathematical relationship between the amount of seal compression and the reliability, and is especially suitable for the high-risk industries such as aerospace and aviation, which require high reliability.
