| چکیده | ||
| خودروهای نظامی برای شرایط بسیار سختی طراحی میشوند که در آن بعضی از کاراییهای خود را از دست میدهند. برای حفظ کار آیی خودروهای نظامی و ادوات همراه طراحیهای مختلفی میشود که باید هزینه آن بهصرفه باشد.چالشی که وجود دارد این است که چگونه میتوان تیرباری را روی خودروی نظامی نصب نمود و در حین حرکت از آن استفاده نمود بهنحویکه دقت تیراندازی قابلقبول باشد. فناوریهای موجود پایدارساز بسیار گران هستند و نسبت به ارزش خودرو و سلاح صرفه اقتصادی ندارند. بنابراین باید روش پایدارسازی غیرفعال با استفاده از اثر ژیروسکوپی را اتخاذ نمود. در این روش از چرخ طیار بزرگ با سرعت دورانی بالا استفاده میشود. شرط اساسی استفاده از این روش تعیین تعداد چرخهای طیار و تعداد قابهای مورداستفاده برای ارتباط بین چرخ طیار و محرک است. در این تحقیق با توجه به شرایط محیطی مدلی جدید از قابها و چرخهای طیار ارائهشده است. این مدل توانایی مقاومت در برابر تحریکات دورانی در دو راستا را دارد. معادله مناسب لاگرانژی آن استخراجشده است. پسازآن چالش اصلی محاسبه آستانه تحمل تحریکات اعمالی توسط سامانه است. این موضوع مهمترین نوآوری این پژوهش است. مدل آزمایشگاهی حل این مسئله و نتایج شبیهسازی عددی ارائهشده است. در انتها پیشنهادها برای ادامه تحقیقات باهدف مقابله با تحریکات در راستاهای دیگر علیالخصوص جابجایی ارائه میگردد. | ||

| چکیده [English] | ||
| Military vehicles are designed for very harsh conditions where they lose some of their efficiency. In order to maintain the efficiency of military vehicles and accompanying equipment, various designs are made that must be cost-effective. The challenge that exists is how to install a shooting range on a military vehicle and use it while moving in such a way that the shooting accuracy is acceptable. The existing stabilizer technologies are very expensive and are not economical compared to the value of cars and weapons. Therefore, passive stabilization method using gyroscopic effect should be adopted. In this method, a large flywheel with high rotational speed is used. The basic condition of using this method is to determine the number of flywheels and the number of frames used for the connection between the flywheel and the driver. In this research, according to the environmental conditions, a new model of aircraft frames and wheels is presented. This model has the ability to resist rotational stimulation in two directions. Its appropriate Lagrangian equation has been derived. After that, the main challenge is to calculate the tolerance threshold of applied stimuli. The laboratory model to solve this problem and the numerical simulation results are presented. At the end, suggestions for continuing research aimed at dealing with provocations in other directions, especially displacement, are presented. | ||
