چکیده

در این مقاله، مدلسازی و تحلیل ارتعاشاتی مجموعه توربین بادی شامل پره‌ها و برج به طور همزمان مورد بررسی قرار می‌گیرد. در مدلسازی پره ها سرعت دورانی آنها نیز در نظر گرفته می شود. ابتدا معادلات توربین بادی در حالت کلی توسط روش معادلات لاگرانژ استخراج و سپس معادلات به روش عددی حل می‌شود. در حل عددی، فرکانسهای طبیعی توربین بادی 5/2 مگاواتی ثامن با استفاده از مشخصات فنی آن استخراج می‌شود. در انتها میزان حساسیت فرکانس های طبیعی اجزای توربین بادی نسبت به پارامترهای اصلی سیستم مانند طول پره، طول برج و جرم مجموعه هاب و ناسل بررسی می‌شود.
