| چکیده | ||
| سکوهای نفتی فراساحلی نقش مهمی در صنعت استخراج نفت و انرژی دارند، به همین دلیل کنترل ارتعاشات این سازه‌ها و افزایش طول عمر مفید آن‌ها از اهمیت فراوانی برخوردار است. در این مطالعه پاسخ دینامیکی سکوی نفتی فراساحلی تحت اثر بار موج با دوره بازگشت 100 ساله بررسی شده است. برای کاهش پاسخ دینامیکی عرشه سکوی نفتی، میراگر جرمی تنظیم شونده نیمه‌فعال خود توان (SP-SATMD[1]) استفاده گردیده و نسبت جرمی آن به صورت پیش فرض 3 درصد در نظر گرفته شده است. انرژی میراگر سیال مغناطیسی (MR[2]) موجود در میراگر جرمی تنظیم شونده نیمه‌فعال از ارتعاش میراگر جرمی و از طریق یک سیستم استحصال انرژی تامین می‌شود. این سیستم شامل ژنراتور جریان مستقیم DC[3]، رک[4] و پینیون[5] است. رک و پینیون حرکت خطی میراگر جرمی را به حرکت زاویه‌ای تبدیل کرده و آن را برای تولید انرژی الکتریکی به ژنراتور DC اعمال می‌کنند. همچنین خود سیستم استحصال انرژی می‌تواند به عنوان یک میراگر الکترومغناطیس (EM[6]) و الگوریتم کنترلی تناسبی در تعیین میرایی سیال مغناطیسی عمل کند. نتایج بیانگر این است که حداکثر جابه‌جایی و شتاب عرشه سکوی نفتی در حالت کنترل نیمه‌فعال خود توان به ترتیب 15 و 24/16 درصد نسبت به حالت کنترل نشده کاهش یافته است. | ||

| چکیده [English] | ||
| Offshore jacket platforms play an important role in the oil and energy industry, so controlling the vibrations of these structures and increasing their useful life is of great interest. In this study, the dynamic response of an offshore jacket platform has been investigated under the effect of wave load with a return period of 100 years. To reduce the dynamic response of the platform deck, a self-powered semi-active mass damper (SP-SATMD) was used and its mass ratio was set to 3% by default. The magneto-rheological damper (MR) energy in the semi-active tuned mass damper is supplied by the vibration of the tuned mass damper (TMD) through an energy harvesting system. This system includes DC direct current generator, rack, and pinion. The rack and pinion convert the linear motion of the TMD into an angular motion and apply it to a DC generator to generate the required electrical energy. The energy harvesting system can also act as an electromagnetic damper (EM) and a proportional control algorithm in determining the damping of the magneto-rheological damper. The results show that the maximum displacement and absolute acceleration of the deck of the controlled platform with a semi-active control strategy decreased by 15 and 16.24%, respectively, compared to the uncontrolled structure. | ||
