摘　　要：本文利用“对振式可控力矩横摇激振装置”进行船模允许甲板入水的强制横摇实验研究，证实用甲板未入水的横摇模型预报允许甲板入水的横摇将产生显著的差别。唯有通过船模允许甲板入水的强迫横摇实验才能获得真实的非线性横摇模型，据此才能进行可靠的巨幅横摇响应预报。This paper presents the experiment investigation of the forced model roll tests allowing of deck into water, using a roll-exciter of contrary vibration type with controllable moment. It is demonstrated that using the roll model of dry deck to pindict the rolling response with deck into water may produce significant error. Through the forced rolling experiments of ship model with deck into water, the realistic nonlinear roll model can be obtained, and the reliable roll response with large amplitude can be predicted.
