结构可靠性定寿模型及其在航空动力结构中的应用

A STRUCTURE LIFE EVALUATION MODEL AND ITS APPLICATION TO DYNAMIC COMPONENTS OF AIRCRAFT POWERPLANT

本文以安全寿命定寿，以损伤容限保障安全，发展了结构可靠性定寿模型，给出了确定结构首翻期和检修周期公式；

The life of a structure is evaluated with its safe-life design,and its safety is ensured with the damage tolerant design,so the safe-life design and the damage tolerant design are combined and a structure life evaluation model is developed. The formulas to determine the service life and the inspection periods of a structure with the high reliability are presented.Then the model is applied to evaluating the inspection periods for aircraft powerplant dynamic components, and an example is given.
