| 摘 要： | 采用基于三维频域线性水动力理论的波浪载荷计算软件Wave Loads Calculation System对1 600 t全回转浮吊船进行了波浪载荷计算(主要指垂向弯矩与剪力),得到不同工况下载荷分布的特点.并将计算结果与中国船级社《钢质海船入级规范》中的规范计算结果进行了比较.研究表明:起重船由于其船型、质量分布和载荷工况不同于运输船,规范计算公式无法对其波浪载荷做出合理评估,而采用直接计算方法,能够根据装载状态,较为准确和详细地预报船体波浪载荷及其分布.

| Abstract: | The WALCS software based on three-dimensional linear potential flow theories is applied to carry out the calculation of wave loads for a 1600t floating crane barge and the characteristics of load distributions under different operating conditions are obtained.The calculated results are compared with the ones calculated by Rules.The study shows that due to the great difference of the mass distributions and loading conditions between floating crane and transport ships,the simplified formula of Rules can not a... |
