در این مقاله، کنترل غیرفعال و فعال ارتعاشات ناشی از جدایش گردابه­های یک استوانه دایره­ای که آزادانه در جهات طولی و عرضی نوسان می­کند، توسط جاذب انرژی غیرخطی مورد مطالعه قرار گرفته‌ ­است. جاذب انرژی غیرخطی از یک جرم، میراگر و یک فنرغیرخطی تشکیل شده که در داخل استوانه مرتعش متصل می­شود. انرژی ارتعاشی استوانه به جرم جاذب انتقال پیدا کرده که در نتیجه آن نوسانات استوانه کاهش پیدا می­کند. به منظور بررسی هر چه بهتر اثربخشی روش کنترلی ارائه شده، نتایج برای چهار عدد رینولدز واقع در ناحیه قفل شدگی فرکانسی Re = 85, 90, 95, 100 ارائه شده است. با توجه به شبیه‌­سازی­‌های عددی، پارامترهای بهینه شده برای جاذب غیرفعال برابر با ... در نظر گرفته می­شود. در ادامه مشاهده می­شود که در تمامی اعداد رینولدز بررسی شده، سیستم­‌های جاذب انرژی فعال نسبت به جاذب انرژی غیرفعال عملکرد بهتری در کاهش ارتعاشات ناشی از جدایش گردابه‌­های استوانه دایروی از خود به نمایش می­گذارند.
