Fundamental mistuning model for determining system properties and predicting vibratory response of bladed disks

摘要: A reduced order model called the Fundamental Mistuning Model (FMM) accurately predicts vibratory response of a bladed disk system. The FMM software may describe normal modes and natural frequencies mistuned using only its tuned system frequency mistuning each blade/disk sector (i.e., frequencies). identification methods—basic advanced ID methods—use mistuned) to determine as well frequencies. predict how much will vibrate under operating (rotating) conditions. Field calibration testing blades be performed traveling wave analysis methods. can generated completely from experimental data. Because FMM's simplicity, no special interfaces are required for compatible with finite element model. rules governing abstracts, this abstract should not used construe claims.
