| 摘 要： | 在导管架下水运动过程中,其组成杆元相对于海平面的位置复杂多样。在导管架下水参数计算和仿真时,为了计算导管架的浮力和浮心,经常采用估算的方法,由于误差比较大而影响了计算和仿真的精度。分析了导管架下水运动过程中杆元的各种状态,用解析的方法推导出导管架下水运动过程中的浮力和浮心的精确计算公式,提高了导管架下水参数计算及其模拟的精度。

| Abstract: | During the launching of jackets,since the location of the structuring poles of jackets has various kinds,a method of estimation is often adopted to calculate the buoyancy and its center of the jacket for analysis of parameters and simulation of launching jackets,and the precision is affected due to big errors.In this paper,all kinds of the status of poles of launching jackets in sea are listed and analyzed.With the analytic method,the expressions for the precise calculation of buoyancy and its center of launching jackets are deduced and given,with which the calculation and simulation for launching jackets become more precise. |

| Keywords: | launching of Jacket platform buoyancy poles precise calculation |
