| 摘 要： | 三立柱轻型半潜式生产平台是一种新型多功能高效平台,可广泛用于中等水深及深水边际油气田开发。但在一定的来流条件下,立柱后方会产生漩涡脱落,导致平台发生涡激运动现象,从而影响平台的海上作业。基于分离涡模拟(detached eddy simulation,简称DES)方法,对具有三立柱和深吃水特点的非传统型半潜式生产平台的涡激运动响应特性开展数值模拟研究,从运动响应幅值和频率、运动轨迹及水动力系数等多个角度分析其在不同流向角和不同折合速度下涡激运动响应的关键特征和锁定范围。研究表明,三立柱轻型半潜式生产平台的横向运动响应由其受到的脉动升力主导,在折合速度7.0≤Ur≤10.0区间内发生锁定现象,且在180°流向角时幅值达到最大,约为立柱直径的59%;首摇运动在0°流向角时达到最大响应幅值4.9°,且锁定区内的响应频率接近其首摇运动固有频率;其运动轨迹主要表现为沿着横向的直线往复运动。
