Computer Programs for Estimation of the Flutter and Divergence Boundaries from Random Responses at a Subcritical Range

摘要

A set of computer programs for a method of estimation of the vibration characteristics and boundaries for flutter and divergence of an aeroelastic system subjected to stationary random noises is described. The programs listed are those for the calculations of the autocovariance function of a time series and Jury's stability parameters of the characteristic equations of fourth and eight orders, and those for the estimation of the stability boundary, frequency and damping ratio of the system.
