摘要： 分析了台架模拟船舶横摇方程参数的方法，依据此原理对船舶—水舱系统数学模型进行研究，求得其横摇阻尼力矩系数。利用缩尺比计算出台架—水舱模型横摇阻尼系数，并针对台架无阻尼项的特点推导了物理系统的传递函数。分析了台架—水舱模型和船舶—水舱模型的仿真曲线，对比其输出统计数据，研究结果表明二者的输出具有一致性。

Abstract: The method for simulating parameters of ship’s roll equation with the platform is analyzed. The mathematical model of ship-tank system is studied based on this principle, and its damping moment coefficient obtained. The damping coefficient of platform-tank model is calculated with a reduced scale. Additionally, aiming at the characteristic of platform without damping item, the function of the physical system is derived. Simulation curves are analyzed and the statistical data compared. The results show that output of the platform-tank model is consistent with that of the ship-tank model.

Key words: anti-rolling tank, platform, damping coefficient
