| چکیده | ||
| در این تحقیق، هدف اصلی، بررسی پارامترهای جذب انرژی پوسته‌های استوانه‌ای فولادی پرشده با پلی‌اتیلن است. بدین منظور از آزمایش‌های تجربی و شبیه‌سازی عددی استفاده شد. به‌منظور مقایسه عملکرد جذب انرژی، نمونه‌های پوسته استوانه‌ای فولادی توخالی و چهار نمونه پوسته استوانه‌ای فولادی پرشده با پلی‌اتیلن ارتالون با سوراخ‌کاری‌های مختلف محوری در قسمت پرکننده تحت آزمایش شبه استاتیکی فشاری قرار گرفتند و با یکدیگر مقایسه شدند. شبیه‌سازی عددی نیز به کمک نرم‌افزار ABAQUS انجام شد و از نتایج آزمایشگاهی برای خواص مکانیکی مواد استفاده شد. نتایج حاصل از شبیه‌سازی عددی همخوانی خوبی را با نتایج تجربی نشان داد. همچنین نتایج نشان دادند که استفاده از پرکننده پلی‌اتیلن در نمونه‌های پرشده سبب کاهش در مقادیر نیروی بیشینه لهیدگی اولیه، افزایش مقادیر میانگین نیروی لهیدگی، کاهش در جذب انرژی، افزایش بازده نیروی لهیدگی نسبت به نمونه‌های خالی می‌شود. به‌عنوان‌مثال، در نمونه پرشده با پلی‌اتیلن و دارای پنج سوراخ محوری در مقدار نیروی بیشینه لهیدگی 5/60% کاهش و در بازده نیروی لهیدگی 77/166% افزایش نسبت به نمونه خالی مشاهده شد. همچنین در بین نمونه‌های پرشده با پلی‌اتیلن، نمونه دارای پنج سوراخ محوری دارای بیشترین بازده نیروی لهیدگی بود. | ||

| چکیده [English] | ||
| In this research, the main goal is to investigate the energy absorption parameters of cylindrical steel tubes filled with polyethylene. For this purpose, experimental tests and numerical simulation were used. In order to compare the performance of energy absorption, empty steel cylindrical tube specimens and four type of steel cylindrical tube filled with polyethylene specimens with different axial perforations in the filling part were subjected to quasi-static compression test and compared with each other. Numerical simulation was also done with the help of ABAQUS software and experimental results were used for the mechanical properties of materials. The results of the numerical simulation showed a good agreement with the experimental results. Also, the results showed that the use of polyethylene filler in the filled samples causes a decrease in the initial peak crushing force values, an increase in the mean crushing force values and also a decrease in energy absorption, and an increase in the crushing force efficiency compared to the empty samples. For example, in the sample filled with polyethylene and having five axial holes, there was a 60.5% decrease in the maximum crushing force and an increase in the crushing force efficiency by 166.77% compared to the empty sample. Also, the samples with five holes have the highest crushing force efficiency among the samples filled with polyethylene. | ||
