Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
This paper extends the transfer matrix technique (TMT) to the shock response analysis of a large complex propulsion shaft system under base shock excitations by a transfer matrix-Newmark formulation itegration method. In order to eliminate the numerical instability of TMT, the transfer vector {fT : ëT}T is used, instead of the traditional one {fT : eT}T. For the shock response computation of the propulsion shaft, a comparison between taking and not taking bearing length into account was performed. Time-varying responses including deflection, acceleration and stress were obtained. The results agree well with those by FEM. The main conclusion is that bearing length has an obvious influence on system responses. The maximum deflection is located at the propeller station.
