Abstract
A set of new procedures is developed to find the probabilities of extremely high amplification factors in mistuned bladed disk vibration levels, which rarely occur. While a rough estimate can be made by curve-fitting the distribution function, the method presented here can determine an accurate upper bound and the probabilities of amplification factors near to that bound. Two examples are provided to illustrate the efficiency of the method, which can be 2 or 3 orders of magnitudes more efficient than Monte Carlo simulations.
