Abstract

This paper deals with efficient computation of the statistics of the normalized peak maximum amplitude (npma) for a bladed rotor with geometric mistuning. The method is based on the high-fidelity reduced-order model, Modified Modal Domain Analysis (MMDA). It is shown that the statistical distributions of npma from random permutations of blades, which do not require any additional finite element sector analysis, are close to those from conventional Monte Carlo simulations in which coefficients of proper orthogonal decomposition features of geometric mistuning are randomly selected.
