Abstract
The paper describes the analytical tools developed for the structural dynamic analysis of machines with rotating parts such as aircraft engines. The finite element analysis is used for discretization, and the rotating parts are described using a 3-dimensional formalism which includes in the kinetic energy expression the gyroscopic effects induced by the local changes of angular velocity produced by the deformation. The implementation of the formalism is specialized to the modelling of flexible rotors made of shafts and disks as it is typical for modern aircraft engines.
