| 摘 要： | 针对顶推船队进行联结力计算.采用切片理论分别计算推船和驳船的附加质量、阻尼系数和波浪扰动力,建立推轮和驳船的耦合运动联立方程,在不同海况和航行条件下计算联结力,并与实验进行了比较.计算结果表明,首斜浪联结力最大;航速越大,联结力越大;波高越大,联结力越大.参照试验数据,提出简单的联结力估算公式.

| Abstract: | The connecting forces are calculated aimed to the tug and barge.The added mass, damping coefficients and sea forces of the bug and the barge are calculated respectively based on Strip Theory.Then the coupling equation of these two ships is proposed and the connecting forces at different sea conditions and navigating conditions are calculated and compared with the test results.The calculating results show that the connecting forces in bow oblique seas are maximal;and the connecting forces will grow up with the increase of velocity and wave height.Referring to the testing data,a simple connecting forces estimating formula is established. |
