Generalized Modes in Time-Domain Seakeeping Calculations

摘要

PUBLISHED IN THE DECEMBER 2012 JOURNAL OF SHIP RESEARCH The concept of "generalized modes" is to describe all degrees of freedom by mode shapes and not using any predefined shape, like rigid body modes. Generalized modes in seakeeping computations allow one to calculate the response of a single ship, springing, whipping, multibody interaction, etc., using a uniform approach. The generalized modes
