| 摘 要： | 本文研究的火箭发射平台主体,为六立柱半潜型式。波高相对于特征长度为小量,考虑到波浪对平台主体大尺度结构的辐射和绕射作用,采用三维频域势流理论对其波浪载荷进行计算分析。对于横撑等小尺度构件,其直径远小于波长,波浪的绕射效应可以被忽略,而粘性作用十分重要,采用了修正的Morison方程对其求解。计算分析结果将为火箭发射平台水动力性能研究提供参考。

| Abstract: | The sea-launching platform studied in this paper is a semi-submersible type floating platform. The wave height is small relative to the characteristic length of platform. Besides, this platform was modeled by the SESAM software to analyze the wave loads considering the radiation and diffraction effects of waves. For small-scale components such as cross braces, the diameters are much smaller than the wavelength, the diffraction effect can be ignored, but stickiness is very important, so the modified Morison equation is used to calculate the wave loads. The results of this study can provide reference for the hydrodynamic analysis of semi-submersible sea-launching platform. |
