| چکیده | ||
| مکانیزم‌های منعطف به دلیل ساختار یکپارچه‌ای که دارند، برای موقعیت‌دهی دقیق و تقویت دامنه عملگرهای پیزوالکتریک طراحی و استفاده می‌شوند. مدل‌سازی رفتار سینماتیکی این مکانیزم‌ها به دلیل ساختار پیوسته و تغییر شکل الاستیک دارای چالش‌‌هایی می‌باشد. در این مقاله ابتدا روشی بر مبنای ماتریس ساختاری به نام روش الاستواستاتیک برای مدل‌سازی استاتیکی مکانیزم‌های منعطف ارائه می‌گردد. نوآوری این مدل، در کاهش محاسبات، با به‌کارگیری تقریب چرخش و جابه‌جایی کوچک می‌باشد. به دلیل ساختار یکپارچه و ساده، مکانیزم لوزی برای موقعیت‌دهی میکرونی و تقویت دامنه عملگرهای پیزوالکتریک مورد استفاده قرار می‌گیرد. هدف اصلی، طراحی و بهینه‌سازی ابعادی مکانیزم منعطف لوزی با استفاده از مدل‌سازی الاستواستاتیک می‌باشد. هدف از بهینه‌سازی ابعادی، دستیابی به بزرگ‌نمایی بالا و سختی ورودی کم می‌باشد تا استفاده از مکانیزم منجر به کاهش دامنه مؤثر پیزوالکتریک نگردد. برای این مکانیزم مدل المان محدود و همچنین مدل تجربی ساخته شده، و در نهایت، خطای مدل‌سازی الاستواستاتیک با شبیه‌سازی در نرم‌افزار المان محدود و نتایج تجربی مقایسه می‌شود. نتایج گرفته شده از آزمونهای تجربی نشان می‌دهد که مدل‌سازی انجام شده برای مکانیزم لوزی حدود 1.5درصد خطا دارد. | ||

| Compliant mechanisms are designed and used for precise positioning and amplification of piezoelectric actuators Due to their integrated structure. Modelling the kinematic behaviour of these mechanisms has challenges due to their continuous structure and elastic deformation. This article presents a structural matrix-based method called the elastostatic method for static modelling of compliant mechanisms. The innovation of elastostatic modelling reduces calculations by approximating rotation and small displacement. The main goal of this research is to design and optimize the rhombus flexible mechanism using elastostatic modelling. This mechanism is optimized in such a way that, in addition to positioning, it has high magnification and low input stiffness. The rhombus mechanism has an integrated and simple structure and is used for micron positioning and piezoelectric actuator amplification. In this research, the rhombus mechanism has been modeled using the elastostatic method, and its dimensions have been optimized according to the parameters of the mechanism; For this purpose, it is necessary to check the modeling error. The modelling error is compared with simulation in finite element software and experimental results. The results show that the modelling used to design the rhombus mechanism has a 1.5% error compared to experimental results. | ||
