| 摘 要： | 针对实船测试数据反映出的中拱、中垂变形会对测深表的精度产生影响的问题,采用曲线拟合的方法精确计算船舶的实际倾斜状态,计算结果表明,使用经过曲线模拟推导出的纵倾修正公式后,计算的舱容数据更接近实际情况。通过这种方法可以有效减少中拱中垂对测深表的影响。

| Abstract: | According to the feedback from delivered ship the sagging and hogging deflection of ship will affects the accuracy of sounding tables.By using the method of curve fitting,the actual inclination of ships can be found to reduce error in calculation of the tank capacity.The results showed that after using this trim modified formula deduced by curve fitting,the calculated tank capacity is closer to the actual value,so this method can be effectively reduced the influence of sagging and hogging deflection of ship upon the sounding tables. |

| Keywords: | sounding table sagging and hogging trim correction curve fitting capacity calculation |
