特定航线江海通航船波浪载荷研究

Study on ship wave loads of specific route river-sea-through ships

为了能对江海通航船型的结构强度进行合理评估,根据载荷第一原则,按特定航线所在的E1海区的波浪统计资料,对该海区船舶的波浪载荷进行了系统研究,并给出了航行于该海区江海通航船的波浪附加弯矩、波浪附加剪力、波浪水平弯矩及波浪扭矩的长期预报值.本文的研究结果已纳入中国船级社《特定航线江海通航船检验指南》中,对特定航线江海通航船的发展起到了积极的推进作用.

In order to carry out a reasonable assessment on structural strength of river-sea-through ships, according to wave statistics of E1 sea area, ship wave loads were studied based on the first principle of loads. Further-more, the long-term prediction values of wave additional bending moment, wave additional shear, wave horizontal bending moment, and wave torsion moment were put forward in this sea area. The results have been included in the Inspection Guide for Specific Route River-sea-through Ships of CCS （China Classification Society）. They may push forward the development of the river-sea-through ships.
