考虑挠度的船舶排水量计算新方法

New Calculation Method of Ship Displacement with Deflection

为获得船舶在存在挠度情况下更加接近真实的排水量,对船舶挠度分布进行研究,并使用积分法计算挠度情况下的实际排水量,介绍船舶产生的挠度对排水量计算结果的影响,并提出排水量计算中挠度修正的新方法。使用新方法计算的船舶排水量与积分法计算的排水量进行比较,明显减小了船舶挠度的影响,进而提高了排水量计算的精度。

In order to obtain the closer result of ship＇s displacement to the actual one under the deflection condition,the ship deflection distribution is studied.The actual displacement under the deflection condition is calculated by the integral method.The influence of the deflection generated by the ship on the calculation result of the displacement is introduced,and the new calculation method of displacement under deflection condition is proposed.The ship displacement calculated by the new method can be found to significantly decreasing the influence of the ship＇s deflection by comparing with the displacement calculated by the integral method,thereby improving the accuracy of the displacement calculation.
