Abstract

When performing operations such as drilling in the ocean, floating platforms undergo vertical motion due to waves, which negatively impacts these operations. So passive heave compensator(PHC) is used to counteract it. In many studies, the analysis of PHC with pneumatic springs has been done. Some of these papers analyzed it using simple second-order differential equations, but there was no case of modeling considering the pneumatic spring installed tilted in the PHC. On the other hand, in some papers, the characteristics were analyzed by numerical methods using multi-body dynamics equations, and it is time consuming. Therefore, in this paper, a second-order ordinary differential equation modeling method for PHC with an inclined pneumatic spring was presented and verified by comparison with the numerical method. Using the model presented in this paper, it is possible to analyze as accurate as conventional analytical methods, and to analyze characteristics faster than numerical methods.

采用分析方法对倾斜活塞运行的被动式波浪补偿器进行性能分析

在海洋中进行钻探等作业时，浮动平台会因海浪而发生垂直运动，这对作业造成了负面影响。因此，被动式波浪补偿器（PHC）被用来抵消这种影响。许多研究都对使用气动弹簧的 PHC 进行了分析。其中一些论文使用简单的二阶微分方程进行分析，但没有考虑到气动弹簧倾斜安装在 PHC 中的情况。另一方面，在一些论文中，使用多体动力学方程通过数值方法对特性进行了分析，但这非常耗时。因此，本文提出了带倾斜气动弹簧的 PHC 的二阶常微分方程建模方法，并通过与数值方法的比较进行了验证。利用本文提出的模型，可以实现与传统分析方法一样精确的分析，并能比数值方法更快地分析特性。
