Papers by Keyword: Transfer Matrices

Abstract: The method of transfer matrices used for torsion vibration of ships complex shafts was analyzed, and various simplified models of transfer matrices were obtained by building a hybrid model for lumped parameter elements and distributed parameter elements. Based on the above, verified by an example of a complex shaft with one propeller driven by two turbines, the method of simplifying model was provided by analyzing the calculation results on the different simplified models.

Abstract: The Dynamic Damage Locating Vector (DDLV) technique localizes damage by interrogating changes in transfer matrices
G. It is shown that although
G cannot be computed in a stochastic setting a surrogate matrix whose null space is related to that of
G can be extracted and this matrix suffices. The paper reviews the theoretical support for the DDLV approach, discusses the constraints used to obtain the surrogate for
G, and illustrates the technique using a 12-DOF shear beam monitored with 6 sensors.
