Abstract:
Theoretical and experimental research on steady vibration response of
shipping propulsion shafting with local nonlinear characteristics are
done. Owing to the coupling with the nonlinear characteristics, it is
difficult that steady vibration response of the shafting is got fen by
regular solutions. On the basis of GLM (Galerkin – Levenberg –
Marquardt) method, a new method that is called the separating and
transform algorithm is proposed and programmed. It can be used for
calculating steady vibration response of the shafting with the coupling.
Steady vibration response of a single disk rotor is calculated using the
program and is tested. The results show that the method and the program
are useful for calculating steady vibration response of the shafting
with local nonlinear dynamic stiffness and damping. Theoretical results
obtained by calculating are coincident with experimental one.
