چکیده مقاله :
The purpose of this article is modal analysis of ionic polymer metal composite beams, then briefing the system to the unique parameters to help in up modeling of the actuator. In this paper at first using of Mathematical analysis and Closed form transfer function of cantilever beam dynamic response to the forces of different inputs (intensive and continuous) is calculated and for different types of systems resonance and anti-resonance points in frequency analysis are found, then with using modal analysis of system the entire response is briefed in the basic mode and parameters of un-damped natural frequency and damping coefficient in this mode is to introduced for the system, after the cantilever composite beam considered as an operator with the input voltage, displacement and produces a force on the free end, By observing the behavior of the system, analyzed responses to the inputs
هدف این مقاله تحلیل مودال تیر از جنس پلیمر-یونی فلزی است، سپس سیستم را به یک مود با پارامترهای منحصربهفرد خود خلاصه کرده تا در شبیه سازی عملگر به ما کمک کند. در این مقاله ابتدا با استفاده از تحلیل ریاضی و فرم بسته تابع تبدیل سیستم تیر یکسر گیردار، پاسخ دینامیکی آن را به نیروهای ورودی مختلف (متمرکز و پیوسته) محاسبه کرده و برای انواع مختلف سیستم، نقاط تشدید و ضدتشدید را در تحلیل فرکانسی پیدا میشود، سپس با استفاده از آنالیز مودال در سیستم، کل پاسخ آنرا در مود پایه خلاصه کرده و پارامترهای فرکانس طبیعی نامیرا و ضریب میرایی در این مود برای سیستم معرفی میشود، سپس تیر یکسرگیردار کامپوزیتی را به عنوان یک عملگر در نظر گرفته میشود که با ولتاژ ورودی، تغییر مکان و نیرو در سر آزاد خود ایجاد میکند که با بررسی پاسخها به ورودیها، رفتار سیستم تحلیل میشود
