Abstract

This paper presents an analytical investigation of the problem of estimating the linearized inertia, damping and stiffness coefficients of a bearing oil film. The principle of structural identifiability has been used to define and compare the conditions to be fulfilled in order to estimate the coefficients when using various types of test signal. The analysis demonstrates the limitations of many standard methods for determining the coefficients and shows how these restrictions can be overcome by using pseudo-random binary sequence forcing. The necessity is stressed for parameter estimation to be performed without any prejudgement of the significance of particular coefficients. It is shown that this basic requirement can be satisfied by using modern parameter estimation techniques.
