3000吨级海上巡视船耐波性分析

以3 000吨级巡视船为研究对象,运用三维水动力理论对其耐波性能进行了数值计算。文中除了给出零航速时船体垂荡、横摇、纵摇与参考点垂向运动的传递函数（RAO）,还进一步进行短期预报,给出航速为0 kn、13 kn、15 kn与18 kn时船体横摇、垂荡、纵摇与参考点垂向加速度的有义值,并与模型试验结果进行对比分析。结果表明：水动力预报值与模型实验值的趋势基本一致。

Seakeeping performance of 3 000 t offshore patrol vessel

This paper carries out the seakeeping performance of a 3 000 t patrol vessel by the three-dimensional hydrodynamic theory. In addition to the response amplitude operators of heave, roll, pitch and vertical motion of reference points at zero speed, it also show their significant value at 0 kn, 13 kn, 15 kn and 18 kn, and compares with the model test results. It shows that the results of hydrodynamic prediction is in accordance with those of the model tests.
