| 摘 要： | 国内同行中有一种观点认为DFR法不适合军机结构，本文根据作者对军机结构疲劳寿命设计分析的多年工程实践，体会到DFR法不仅适用于民机结构，也适用于军机结构。为此，作者总结了DFR法在军机结构疲劳寿命分析中一系列成功应用范例，指出DFR法具有其他方法无法比拟的优越性：实用性、简捷性、可靠性和普遍性。

| Abstract: | Depending on many-years experiences of engineering practice, the author considers that the method of DFR is not only applicable in the civil aircraft structure, but also the same with military aircraft structure. Therefore, the author summarizes a series of successful examples of the method of DFR in the fatigue life analysis for the military aircraft structure, pointing out the method of DFR has a lot of advantage in which the other methods can not compare with it： practicability, concision, reliability and catholicity. |
