摘要
本文提供了小水线面双体船 (SWATH)结构载荷的解析方法以及用于初步设计的简捷算法经验公式。确定船体运动和波浪载荷的方法是以谐波中船舶的线性响应为基础 ,按零航速横浪来计算的。根据模型试验结果此种状态是 SWATH最危险的载荷状态。以前应用于 30 0 0～ 30 0 0 0 t船的经验算法往往被不正确地用于小吨位的船上 ,文中提供了一个新的经验算法可将应用界限扩展到小如 5 0 t的 SWATH船上。
This paper present the analytical method for structural load calculation for SWATH ship, and the short cut method with empirical formula for preliminary design. The acquisition of ship motion and wave loading is based on the linear response of ship in harmonic wave and calculated by ship with no speed running beam sea, which is believed the most dangerous loading condition for SWATH ship according to the ship model testing results. Since the empirical algorithm for 3 000～5 000 tonnage ships is often ill used in the design of small ships, the new empirical algorithm can be expanded to the design of SWATH ship as small as 50 tonnage size.
