Abstract

Development of submarine and its safe operational envelope requires an understanding of motion characteristics including emergency rising motion. In this study, the emergency rising motion is investigated using submarine free-running model equipped with ballast systems. The emergency rising test was conducted according to the initial vehicle speed, yaw rate, depth, ballast water discharge ratio and time interval between bow and stern ballast systems. Experimental results reveal that the maximum pitch angle before surface is affected by initial velocity and the operation conditions of ballast systems. In addition, excessive roll occurs after the surface when the submarine passes through the water surface at a negative pitch angle. Furthermore, the system parameters that comprise the emergency rising model are estimated using the collected test data. The identified model is verified by comparing emergency rising simulation with the free-running model test results.

基于自由运行模型的潜艇应急上升运动实验与建模

潜艇及其安全操作包线的发展需要了解包括紧急上升运动在内的运动特性。本文采用装有压载系统的潜艇自由运行模型，研究了潜艇的应急上升运动。根据船舶初始航速、横摆角速度、深度、压载水排放比和船首尾压载系统间隔时间进行应急上升试验。实验结果表明，初始速度和压载系统运行条件对最大俯仰角有一定的影响。此外，当潜艇以负俯仰角通过水面时，水面后会出现过大的横摇。此外，利用收集到的试验数据估计了构成应急上升模型的系统参数。通过应急上升仿真与自由运行模型试验结果的对比，验证了所识别的模型的正确性。
