✦ Synopsis

The mathematical foundations for experimental modal analysis of rotating structures are presented. They are characterised by non-symmetric and time-variant matrices. The equations of motion are solved by modal transformation to derive impulse and frequency response functions, which form the basis of modal identification algorithms in time and frequency domains, respectively.

Static indetermination is a common problem in the dynamic analysis of most multibearing rotor systems. This paper presents a systematic treatment of this problem. It is taken into account at the stage when the general mathematical model is constructed for a complete multi-bearing rotor system. The p
