Abstract
در این پژوهش، رفتار چرخه ای میراگرهای فولادی تسلیمی شکاف دار مورد بررسی قرار می گیرد. میراگرهای مورد مطالعه دارای شکاف مستطیلی، بیضوی و نامنشوری می باشند. میراگرهای موردنظر به طول 420، عرض 320 و ضخامت 6 میلیمتر در نظر گرفته شده اند. از هر نوع از میراگرهای شکاف دار 3 مدل عددی با ابعاد شکاف متفاوت به صورت عددی در نرم افزار آباکوس مدلسازی و رفتار چرخه ای آن ها با یکدیگر مقایسه می گردد. سپس میراگرهای فولادی دارای مقاومت بالاتر از هر نوع انتخاب و مقدار جذب انرژی چرخه ای آن ها با یکدیگر مقایسه می گردد. شایان ذکر است برای مقایسه مقدار جذب انرژی نمونه های مورد نظر از ضریب استهلاک انرژی استفاده می شود.
