海洋表面波是作用于船舶和近海结构物的最重要的外力源之一。大多数海浪是由风产生的,但各种其他效应,如海流、地面和海岸地形、破碎和波浪-波浪相互作用,都会影响特定频率范围内波浪能的增长和消散。这些水波本质上是随机的,即使将所描述的区域限制在很小的范围内,它们的确切形状也很难描述。虽然存在许多不同的方法来描述海浪的光谱特性,但对影响海浪生成的一些过程仍然知之甚少。本文讨论了一些技术,用于描述海浪谱相对于随后的分析动态力学系统在海洋中,如船舶,平台和管道。不同的方法的优点和局限性进行了讨论。(© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA,魏因海姆)
Ocean surface waves constitute one of the most important sources of external forces that act on ships and offshore structures. Most ocean waves are generated by wind, but various other effects such as currents, ground and coastal topology, breaking and wave–wave interaction have an influence on the growth and dissipation of wave energy at specific frequency ranges. These water waves are inherently random in nature and their exact shape is difficult to describe, even when confining the described area to a small range. While many different approaches exist to describe the spectral characteristics of ocean waves, some of the processes which affect the generation of waves are still poorly understood. This paper addresses some techniques which serve to describe seaway spectra with respect to the subsequent analysis of dynamic mechanical systems in the ocean such as ships, platforms and pipelines. Advantages and limits of the different approaches are discussed. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
