系统在海浪中的动力学行为分析是近海工程中的重要组成部分。虽然线性化模型的响应特性可以在频域中获得,但必须注意的是,近海系统通常包括具有非线性行为的部件。系统地分析浮式结构物的非线性动力学往往通过附加的假设来实现。一个常见的例子是使用确定性(谐波)波。尽管周期波对于许多应用来说可能是一种合理的简化,但通常海浪通常更好地用谱或概率方法来描述。本文介绍了浮式结构物分析中描述随机力的不同方法。算例显示了不同的波浪模型对简单浮式结构物分析的影响。(2006 Wiley-VCH Verlag GmbH&Co.KGaA,Weinheim)
The analysis of the dynamical behavior of systems in ocean waves is an important part in offshore engineering. While a characterization of the response of a linearized model can be obtained in frequency domain, it has to be noted that offshore systems usually include components with nonlinear behavior. The systematic analysis of the nonlinear dynamics of floating structures is often facilitated by additional assumptions. One common example is the use of deterministic (harmonic) waves. Even though periodic waves may be a reasonable simplification for many applications, sea waves in general are usually better described by a spectral or probabilistic approach. This paper addresses different methods of describing random forces for the analysis of floating structures. Examples show the effects of different wave models on the analysis of a simple floating structure. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
