Inverse ice-induced moment determination on the propeller of an ice-going vessel

This paper presents inverse methods to determine the ice-induced moment on the propeller based on shaft line torque data. The following methods are applied: Truncation of singular value decomposition (TSVD), truncation of generalized singular value decomposition (TGSVD) and Tikhonov regularization. The dynamic behavior of the structure is modeled by combining an increment form of the governing equation of torsional vibration and Newmark-β...
