چکیده

شبیه­سازهای پروازی هواپیما دارای سامانه حرکتی نقش مهمی در بهبود کیفیت آموزشی، افزایش ایمنی پرواز و کاهش هزینه­های آموزشی را دارند. مکانیزم استوارت، یکی از سامانه­های حرکتی در شبیه­سازها می باشد. این مکانیزم شش درجه آزادی به­دلیل مستقل نبودن درجات آزادی حرکتی سازه،از لحاظ تحلیل‌ دینامیکی و کنترلی دارای پیچیدگی­های خاص خود می‌باشد. در این مقاله یک سامانه حرکتی الکترومکانیکی شش درجه آزادی، به‌صورت کامل طراحی و تحلیل شده است. با در نظر گرفتن سرعت­ها و شتاب­های خطی و دورانی، وزن مجموعه کابین و روابط سینماتیکی دستگاه، حرکت­های فضای کاری سکو آنالیز شده و موقعیت، سرعت و شتاب در هر لحظه محاسبه      می­شود. اثر پارامترهای مختلف مانند زوایای رول، یاو، پیچ، سرعت و شتاب خطی و زاویه ای سکوی بالایی بر روی نیرو و سرعت عملگرها   به­صورت عددی مورد بررسی قرار گرفته است. سپس با استفاده از نیروهای وزن و شتاب­های دینامیکی به­دست­آمده، توان الکتروموتور، طول و قطر بال­اسکرو، تغییر طول پایه­ها، سکوی پایینی و پایه­های رابط تحلیل و طراحی شده­اند.

چکیده [English]

Aircraft flight simulators with motion systems play a major role in improving education quality, flight safety and reducing training costs. Stewart mechanism is one of the simulator motion systems, which is a six-degree of freedom mechanism with coupled structures which makes its dynamical control analysis become more complicated. In this research, an electro-mechanical motion mechanism with six degrees of freedom has been completely analyzed and designed. With respect to the translational and rotational velocity and acceleration, and weight of cabin complex, kinematic relations of the machine, motions in work space with moving platform have been analyzed to calculate the positions, velocity and acceleration at any moments. The effects of various parameters such as roll, yaw, pitch, the linear and angular velocity and acceleration of the top platform on the force and speed of the operators are numerically studied finally. its components, namely electro-motor power, the length and diameter of ball screw, legs lenghth, lower platform, and leg linkage variations are, were analyzed and designed.
