【摘要】：文章應(yīng)用水動(dòng)力學(xué)軟件AQWA對(duì)在隨機(jī)波浪荷載和風(fēng)、流荷載聯(lián)合作用下的浮動(dòng)式發(fā)電平臺(tái)的穩(wěn)定性進(jìn)行研究,分析了5種工況下該平臺(tái)遭遇迎浪(0°浪向角)、艏斜浪(45°浪向角)、橫浪(90°浪向角)時(shí)的橫蕩、縱蕩、艏搖運(yùn)動(dòng)響應(yīng)幅值,比較了該平臺(tái)在破損工況(有系泊纜斷裂工況)和完整工況(無(wú)系泊纜斷裂工況)下的運(yùn)動(dòng)響應(yīng)幅值。結(jié)果表明:平臺(tái)的艏搖、橫蕩和縱蕩運(yùn)動(dòng)響應(yīng)的最大值分別發(fā)生在遭遇艏斜浪、迎浪和橫浪時(shí);在系泊纜斷裂瞬間該平臺(tái)所有方向運(yùn)動(dòng)響應(yīng)均有大幅增加,其中破損自存工況下艏搖運(yùn)動(dòng)響應(yīng)幅值是完整工況下的6~7倍。
[Abstract]:In this paper, the hydrodynamic software AQWA is used to study the stability of floating power platform under the combined action of random wave load, wind load and current load. The heave, longitudinal and yaw response amplitudes of the platform are analyzed when the platform encounters 0 擄wave angle, 45 擄wave angle and 90 擄wave angle under five working conditions. The motion response amplitudes of the platform under breakage (mooring cable breakage) and intact (no mooring cable breakage) are compared. The results show that the maximum response of yaw, heave and longitudinal motion of the platform occurs when the yawp wave, the swinging wave and the transverse wave are encountered, and the response in all directions of the platform increases significantly at the moment when the mooring cable breaks. The amplitude of the yawing response under the condition of self-stored damage is 7 times higher than that under the intact condition.
