چکیده

در فرآیندهای شکل دهی ورق، تولید قطعات مخروطی-استوانه ای در یک مرحله و با دقت بالا به‌دلیل وجود عیوب چروکیدگی و پارگی بسیار دشوار است. یکی از کاراترین روش ها در میان فرآیندهای هیدروفرمینگ ورق به‌منظور تولید قطعات مخروطی- استوانه ای، روش کشش عمیق هیدرودینامیکی با فشار شعاعی است. در این مقاله مسیر فشار شکل دهی به‌عنوان یکی از مهم‌ترین پارامترهای مؤثر در این فرآیند، مورد بررسی قرار گرفت و در یک روش جدید با ترکیب روش اجزای محدود با استفاده از نرم‌افزار انسیس و بهینه‌سازی با الگوریتم تبرید تدریجی، مسیر بهینۀ فشار به‌دست آمد.
