摘要
为了采用谱分析方法预报海洋结构物和船舶在随机海浪中所受的二阶波浪力,必须先求得海洋结构物和船舶在任意单色波和双色波中受到的二阶波浪力.本文基于严格的量级分析,对有航速的细长体(浮体或潜体),建立由不同浪向双色波作用在细长体上产生的二阶波浪力的切片理论;
In order to use spectral analysis theory to calculate second order wave forces which naval architectures suffered in the random sea waves, the second order wave forces which naval architectures suffered in any one regular wave or any two regular waves should be calculated firstly. In this paper, a strip theory for the second order wave forces on slender bodies advancing in two regular waves from different incident angles was established. As a component of the total second order wave forces, the slowly varying forces on the submerged slender body and their variation in different subemergence and combinations of incident angles were given and discussed.
