| Abstract: | Transient dynamic characteristics and stability of a rotor-support-casing system in an aeroengine are analyzed by means of substructure transfer matrix-modal synthetic method.The effects of various sudden unbalance levels,radial oil film clearances of damper and different rotor speeds on the transient response of the entire engine system are investigated and some valuable conclusions have been drawn.The substructure transfer matrix-modal synthetic method discussed in the paper is available in theory and practice. |
