讨论规则波下某张力腿平台的动力响应时域运动特性。着重分析入射波角度(15°,22.5°和45°),波高(6m,8m和10m)及波周期(10s,12s和14s)对张力腿平台各自由度运动、顶端张力的影响。探讨吃水高度、工作水深、不同张力腿数目对张力腿平台运动特性的影响。计算结果表明：由于张力腿平台各自由度对入射波角度、波高和波周期敏感度不同,张力腿平台在不同波浪参数下的运动特性(如位移幅值、平衡位置等)及顶端张力表现各异；不同吃水下的张力腿平台位移大小、平衡位置和运动方向等均不同。工作水深越大,各自由度运动越剧烈,这体现了工作环境对张力腿平台运动具有较大影响。张力腿数目越多,张力腿平台运动的位移、幅度等越小,随时间变化也越稳定。

Thispaperdiscussesthetimedomaindynamicresponsecharacteristicsofatensionleg platform in the regular wave. The paper focuses on the analysis of the effects of the incident wave angles (15°, 22. 5° and 45°),the wave height (6m, 8m and 10m) and the wave period (10s, 12s and 14 s) on the movement of Tlp, the top tension of the tension leg; and we discusses the influences of the draught height, the water depth, the different tension leg number on the the platform motion characteristics. The results show that: because of the different sensitivity of the tension leg platform to the incident wave angle, the wave height and the wave period, the performance of the motion characteristics and the leg tension ( such as shift range, equilibrium position ) is different. Platform draft effects the shift, the equilibrium position and the movement direction. When the working depth is greater, the platform movement will be severer, which reflects the working environment has a great influence. Tension leg platform each column angle tension when the leg number is smaller, the shift range is smaller and more stable.
