【摘要】 文章对一种深海浮体上浮阻力进行了分析,通过数值计算预报浮体的上浮速度,以此评估浮体上浮过程的安全性。提出了一种基于水下压力检测获取浮体自由上浮过程中稳定速度的方法,通过实尺寸浮体模型水池上浮试验,测量无倾角和带倾角上浮过程的实际稳定速度,比较分析试验结果与理论计算,获取浮体上浮运动的规律,验证浮体安全上浮能力。试验结果表明,该浮体无论是无倾角上浮还是带倾角上浮,其上浮速度均不超过理论计算的稳定速度,安全上浮能力完全达标。更多还原

【Abstract】 In order to evaluate the safety of the floating process,the resistance and velocity of a floating body are analyzed and predicted by numerical calculation.A method based on pressure detecting is proposed to obtain the stable velocity and applied to freely floating experiment of full-size model carried out in a tank.The practical stable velocity with and without inclination angle condition are got to compare with the calculating result.Then the law of floating motion is acquired to verify the safety of floating body.The result of test shows that the floating speed is no more than the stable velocity in whether with inclination condition or not,so the safety of floating makes full compliance.更多还原
