海洋风速动态仿真及其在平台模拟系统中的应用

摘要

In accordance to the requirements of sea wind simulation in an offshore platform simulation system, different kind of wind models are analyzed, in which the combined wind model is chosen as the basic model for present research. The basic combined wind model is improved through the addition of special feature of sea wind, which will change with the height above the surface of the water and various wave conditions. A non-parametric method is given in the simulation of random wind. Simulation of sea wind is carried out after development of a simulation program and determination of the parameters. Simulation result can be obtained quickly, which is reliable and has been applied to the offshore platform simulation system.%针对海洋平台模拟系统中海上风速的动态仿真要求，综合分析多种风速模型，开发了海洋风速动态仿真模型。该模型在组合风速基本模型基础上加以改进，加入海上不同高度风速计算以及海面波浪状态等因素，并导入了无参数化随机风模拟方法。在开发模拟程序、选定参数的基础上，进行了海上随机风仿真模拟，模拟过程快速且结果较为真实，模拟效果良好，并实际应用于海洋平台模拟系统的随机风模拟中。
