为使轴系校中计算模型更接近实船轴系运转工况,确保采用可调桨推进系统的船舶安全运行,在考虑螺旋桨水动力影响下,采用改进三弯矩法对轴系校中数值计算模型进行改进。并以某物探船为例,对其可调桨推进系统进行动态轴系校中计算。数值计算结果显示：考虑螺旋桨水动力等动态因素影响的动态轴系校中计算确保了采用调距桨推进轴系船舶在各种工况下的安全运转。

Application of Shafting Alignment for a Certain GeophysicalVessel with Controlled Pitch Propellers Based on Improved

To insure vessel shafting systems with controlled pitch propellers run safely in the long term, improved three-moment equation method is adopted to establish the numerical model of shafting alignment including hydrodynamic influences in order that the calculated model is as possible as similar to shafting actual situations. And the dynamical shafting alignment of a certain geophysical vessel with controlled pitch propellers is analyzed with improved three-moment equation method. The calculated results show that the dynamical shafting alignment including hydrodynamic influences insures vessel propulsive systems with controlled pitch propeller run safely in different conditions.
