Abstract
Tolerance analysis of mechanical assemblies is an important tool in reliable design of products at low cost and good quality. Using this tool, it is possible in manufacturing stage to observe the effect of parameters on assembly requirements. The direct linearization method is a useful method which runs based on vector loop analysis. In this research, the DLM method is used to analyze the tolerance chain in triggering mechanism assembly. Furthermore the percent contribution of various manufacturing dimensions on the design requirement of the assembly in determined.

Abstract [Persian]
هدف اصلی این مقاله محاسبه نیروها و گشتاور‌های هریک از غلتک‌های فرایند نورد حلقه با هدف طراحی و ساخت دستگاه نورد حلقه برای تولید دو پوسته موتور هواپیما است. برای محاسبه نیروها و گشتاور‌ها، شبیه‌سازی فرایند نورد حلقه شعاعی- محوری دو پوسته موتور هواپیما با استفاده از روش اجزا محدود صورت گرفت. برای اطمینان از نتایج شبیه‌سازی، خروجی‌های حاصل از شبیه‌سازی نورد یک حلقه ساده از جنس Ti-6Al-4V با نتایج تجربی مقایسه می‌شود. پارامترهای مورد مقایسه دمای حلقه و شکل مقطع آن است و مقایسه نتایج حاکی از دقت خوب نتایج و میزان خطای ناچیز آنهاست. همچنین در این مقاله روش جدیدی برای شبیه‌سازی غلتک‌های راهنما بیان شده است که نسبت به روش‌های گذشته دارای سادگی و کارایی بیشتری است.
