Description

一种用于海洋工程模型试验的风场模拟装置A wind field simulator for ocean engineering model tests

技术领域technical field

本实用新型涉及一种用于海洋工程模型试验的风场模拟装置,属于海洋工程技术领域。The utility model relates to a wind field simulation device used for ocean engineering model tests, which belongs to the technical field of ocean engineering.

背景技术Background technique

海洋工程结构物,如海上采油平台、海上风电机组等长期承受风、浪、流复杂环境荷载作用,其相关研究更多地依赖波浪水池模型试验,而模型试验结果的准确性和可靠性与环境荷载模拟装置密切相关,其中风荷载模拟装置便是非常重要的环境荷载模拟装置之一。Ocean engineering structures, such as offshore oil production platforms and offshore wind turbines, have been subjected to complex environmental loads of wind, waves, and currents for a long time. The related research relies more on wave pool model tests, and the accuracy and reliability of model test results are not related to the environment. The load simulation device is closely related, and the wind load simulation device is one of the very important environmental load simulation devices.

对海洋环境风荷载的模拟,通常采用两种基本办法,一种方法是风洞模拟,如哈尔滨工业大学风洞浪槽联合实验室,风洞可以模拟出较高品质的风场,但是其缺陷表现在(1)风洞建设费用和模型试验费用均非常高昂;(2)由于整体造风将干扰波浪的自由面运动而往往导致结构的动力响应失真;另一种方法是目前广泛采用的简易造风装置模拟,由一组或多组风机组成风机阵,放置在池边或拖车上面,靠近试验模型进行局部造风,对于简易造风装置,具有代表性的是文献[1]中描述的装置,其缺陷是没有整流措施品质差,噪音大,受池岸干扰,无测控系统;后来文献[2]做了进一步的改进,增加了整流装置,但是由于没有收缩段和消声器,风速下降非常快,能耗大,噪音大,且无测控系统;For the simulation of wind load in the marine environment, two basic methods are usually used. One method is wind tunnel simulation, such as Harbin Institute of Technology Wind Tunnel Wave Trough Joint Laboratory. Wind tunnels can simulate high-quality wind fields, but their defects It is manifested in (1) the cost of wind tunnel construction and model test is very high; (2) the dynamic response of the structure is often distorted because the overall wind generation will interfere with the free surface motion of the wave; another method is the simple Simulation of wind-generating devices, consisting of one or more groups of fans to form a fan array, placed on the poolside or on a trailer, close to the test model for local wind-generating, for simple wind-generating devices, the representative one is the one described in the literature [1] The defect of the device is that there is no rectification measure, poor quality, high noise, interference from the pool bank, and no measurement and control system; later, the literature [2] made further improvements and added a rectification device, but because there is no contraction section and muffler, the wind speed drops very much. Fast, high energy consumption, high noise, and no measurement and control system;
