چکیده

یکی از روش های جدید برای تامین انرژی سیستم‌های پایش سلامت پل‌ها استفاده از انرژی مکانیکی است. در این روش با استفاده از مبدل پیزوالکتریک، انرژی ناشی از ارتعاشات پل به الکتریسته تبدیل می‌شود. مزیت این روش عدم نیاز به تعویض یا شارژ باتری سیستم پایش سلامت می‌باشد. در تحقیقات پیشین، مطالعاتی بر روی تولید انرژی از ارتعاشات پل‌ها انجام شده است ولی تحقیقی در زمینه‌ی بررسی آماری مقدار انرژی تولید شده با در نظر گرفتن نامعینی در نوع و خواص خودروهای عبوری از روی پل انجام نشده است. بنابراین در این مقاله، مقادیر آماری ولتاژ تولید شده بعد از مدل‌سازی مناسب پل-وسیله نقلیه و برداشت کننده انرژی در حضور تمامی نامعینی‌های موجود در وسیله نقلیه با استفاده از روش مونت‌کارلو، استخراج شده است.

چکیده [English]

One of the new methods for electrical powering of the bridge health monitoring systems is applying energy harvesting systems using bridge vibration. In this method, the piezoelectric material is employed for converting mechanical energy into electrical energy. The advantage of this method is based on not implementing the battery charging system. In previous research, some studies have been done on the energy harvesting from vibration of bridges, however, research on statistical analysis of produced power with considering uncertain vehicle type and specifications has not been considered. Therefore in this paper, after modelling the bridge-vehicle-piezoelectric system with complete vehicles uncertainties, the statistical analysis of produced voltage are carried out by Monte-Carlo simulation.
