When it comes to vibration, no two IBDs are alike. Every IBD has a unique set of properties that causes it to vibrate differently than all other bladed disks, even those of the same design. One of BDC’s objectives is to identify which parts are genetically predisposed to fail from HCF, and then alter them to lower HCF risk.
EzID is a critical tool in this process. EzID performs the vibration equivalent of gene sequencing on an IBD. It works by analyzing a sample measurement of an IBD to determine its Vibratory DNA: a collection of characteristics that determine how that part will vibrate under different conditions. This includes properties such as the frequencies of the individual blades as well as measures of how the motion of the various blades are interconnected.
While a vibration test such as EzVIBES can tell you if an IBD has high vibration, EzID provides essential information to understanding why, and how to fix it.
