تشخیص خرابی سازه تیر با استفاده از تحلیل آماری پاسخ‌های اندازه‌گیری شده و تبدیل هیلبرت-هوانگ

محمدجواد خسرویانی, مجید قاسمی

چکیده


در این مقاله یک روش جدید تشخیص خرابی بر اساس تبدیل هیلبرت- هوانگ پاسخ‌های اندازه‌گیری شده سازه تیر ارائه شده است. توابع مودی ذاتی پاسخ‌های دینامیکی سازه با استفاده از تجزیه مودی تجربی در نقاط مشخص محاسبه شده و تبدیل هیلبرت برای محاسبه دامنه آنی بر روی هر تابع مودی ذاتی به کار برده شده است. ضریب همبستگی و تابع همبستگی متقابل دامنه آنی پاسخ‌های سالم و خراب سازه محاسبه شده‌اند. محل خرابی از طریق تعریف پارامتر شاخص خرابی و مقایسه نمودار آنها در حالت‌های سالم و خراب به دست آمده‌اند. برای ارزیابی و دقت روش یک مدل المان محدود سازه تیر بتنی دو دهانه مدل شده است. پاسخ‌های دینامیکی تیر با استفاده از تحلیل عددی تحت بارگذاری مثلثی مشخص به دست آمده‌اند. با توجه به نوفه‌های اندازه‌گیری، به پاسخ‌های دینامیکی مقادیر نوفه اضافه شده و نتایج مورد بررسی قرار گرفته است. نتایج حاصل نشان دادند که روش ارائه شده محل خرابی را با دقت خوبی تشخیص می‌دهد.
