作为船体响应模态分析的重要初步步骤，找到了拉格朗日意义上对应于对称运动主坐标的广义水动力。这是基于带理论和与 (a) 船舶运动和 (b) 波浪激励相关的广义力来完成的。结果表明，在一定程度上取决于所使用的条带理论公式，流体动力阻尼的模态耦合符合蒂曼和纽曼关系。讨论了这一发现在当前结构动力响应理论中的应用。订购自：BSRA，编号：48,346。
As an essential preliminary step in the modal analysis of hull response, generalized hydrodynamic forces corresponding in the Lagrange sense to the principal coordinates of symmetric motion are found. This is done on the basis of strip theory and the generalized forces relating (a) to ship motion and (b) to wave excitation. It is shown that, depending to some extent on which strip theory formulation is used, the coupling of modes by hydrodynamic damping conforms to the Timman and Newman relationship. The applications of this finding in current theories of structural dynamic response are discussed. Order from: BSRA as No. 48,346.
