| 摘 要： | 以海军某四筒型基础平台为研究对象,在吃水深度、波浪条件和水深一定的条件下,在不同拖航速度下静水、顺浪和逆浪拖航,通过模型试验测定筒型基础平台在横荡、纵荡和垂荡方向上的加速度、筒内气压力和筒底水压力以及拖航中的拖缆力.试验结果表明:静水拖航中,筒型基础平台的拖航速度存在一个上限;拖航过程中的拖缆力随着拖航速度和水质点振荡速度的相对值以及纵荡加速度变化;平台拖航过程遇到大浪情况下,降低拖航速度是保证结构耐波性和稳性的有效方法.

| Abstract: | Using a naval platform with four bucket foundations as the object of study,under the definite conditions of draught,incident wave and water depth,the acceleration of swaying,surging and heaving,the internal air pres-sure and bottom water pressure of the bucket and the towing power of platform were determined in still water,following wave and head wave with different towing speeds.It is shown that there is an upper limited speed in the towing of bucket foundation platform in still water;the tension in towing is related to the relative value between tow-ing speed and oscillation speed of water particles and the changes of the surging acceleration;under the situation of encountering a wave with large height or large period,in order to assure the stability and sea-keeping,reducing the towing speed is an effective method. |
