0 引言 在内河工程船舶的动力装置设计和设备选型中,常常涉及到起重绞车和锚泊定位绞车.根据具体工况,如何快速确定绞车方案,从而确定机舱的动力配备、绞车的布置,是很有意义的.另外,绞车的选型和强度计算比较繁琐,没有统一的标准.本文打算就此谈些设计和选型体会. 相似文献

本文采用数值计算方法对浅水中海洋平台支持船(OSV)的锚泊定位性能开展研究.首先,基于三维频域势流理论,对一艘OSV不同水深的水动力性能开展分析,计算了水动力系数、运动幅值响应算子、一阶波浪力和二阶波浪力.由于浅水中非线性效应显著,本文采用中场公式计算了该OSV全二阶波浪力传递函数(Full Quadratic Transfer Function,简称全QTF).然后,本文对不同水深下锚泊系统的水平刚度开展了分析,计算了不同水深下锚泊系统的水平刚度,研究了水深对锚泊系统水平刚度的影响.最后,采用准动态方法对不同水深下的OSV和锚泊系统开展时域分析,研究了水深对船体运动性能和锚索张力的影响. 相似文献
