| 摘 要： | 直升机动部件的疲劳定寿中,为考虑平均载荷的影响,不可避免地需要采用简化的近似等寿命曲线对疲劳特性和飞行载荷进行修正处理。为防止因修正处理不当而造成影响定寿结论和使用安全,本文对目前国内外常采用的修正方法进行了分析,并提出了工程应用中的处理原则和措施。

| Abstract: | In faligue life evaluation for dynamic components of helicopler.it is inevitable to adopt the simplified approxmate Equivalent Life Curves to make the revision of fatigue properties and flight loads, considering the effect of average loads. In order to avoid theinfluence to the conclusion of the fatigue life evaluation and the service safety caused by incorrect revision, this paper analyzes the revising methods which are frequently uese in the home country and abroad at present, and also gives some principle of treatment in engineering application and measures. |
