结果表明，该干涉图可用于包括长弧罩结构在内的带冠叶片的设计可靠性评估。该方法为广泛使用的Campbell图提供了另一种方法，并为更容易的设计评估带来了更多的信息。SAFE图使用整个刀片磁盘的固有频率，而不是单个刀片或包的频率。此外，它比较频率，模态振型和速度来评估是否发生共振
The SAFE Interference Diagram is shown to be useful in the design reliability evaluation of shrouded blading, including long-arc shrouding construction. This method provides an alternate method to the widely used Campbell diagram and also brings in more information for easier design evaluation. The SAFE diagram uses the natural frequencies of an entire bladed disk rather than individual blade or packet frequencies. In addition, it compares frequencies, mode shapes, and speed to evaluate whether a resonance occurs
