โœฆ Synopsis

The spectral distribution function is used to characterize the vibration signal of rotating machinery. It is shown to be a more robust indicator than conventional power spectral density estimates, but requires only slightly more computational effort. The method is demonstrated with a model of a defective bearing. The spectral distribution function is applied to practical problems involving seeded helicopter transmission faults and the vibration signal from a ground-based vacuum compressor system.

This paper describes a new spectral estimator based on the Fourier transform, the autocoherent spectrum (ACS), which enables the extraction of the pure sinusoidal components with a greater sensitivity and an improved frequency resolution. It's statistical properties are studied, and it is shown how

A systematic method is presented for analyzing the vibration of a rotating, geometrically discontinuous shaft with general boundary conditions. Both the Rayleigh and Timoshenko beam models are considered in the analysis. Exact, closed form solutions for the free and forced responses are obtained by
