摘　　要：为了准确有效地预报作用于多浮体上的瞬态水动力,采用时域理论对海洋石油201船与Spar平台靠近时的水动力干扰进行了数值分析对比。计算采用的软件为Hydrostar水动力分析软件,其基本理论是三维势流理论,采用该软件计算了海洋石油201船与Spar平台的水动力系数,时域脉冲响应函数主要是将频域下的阻尼系数经过半解析方法变换得到。数值算例中,对海洋石油201船和Spar平台在时域中研究了单个浮体和多浮体脉冲响应函数的不同特点。经过对数值结果的比较分析,可以看出多浮体靠近作业时,该计算方法和专业软件的计算相吻合,验证了该计算的准确性,为项目提供了参考依据。In order to accurately and effectively predict the transient hydrodynamic forces acting on multi floating bodies,the timedomain theory is used to analyze and compare the hydrodynamic interference when the offshore HYSY 201 is close to the spar platform.The software used in the calculation is hydrostar hydrodynamic analysis software.Its basic theory is three-dimensional potential flow theory.The hydrodynamic coefficients of offshore HYSY 201 and Spar platform are calculated by this software.The timedomain impulse response function is mainly obtained by transforming the damping coefficients in the frequency domain through thesemi analytical method.In the numerical example,the different characteristics of impulse response function of single floating bodyand multi floating body are studied in the time domain for the offshore HYSY 201 and spar.Through the comparative analysis of thenumerical results,it can be seen that the calculation method of this paper is consistent with the calculation of professional softwarewhen the multi floating body is close to the operation,which verifies the accuracy of this paper and provides reference for the project.
