چکیده

در پژوهش حاضر به بررسی رفتار مخازن گاز طبیعی فشرده نوع اول تا چهارم خودروها تحت اثر فشار داخلی و بار انفجاری خارجی در نرم افزار اجزای محدود آباکوس پرداخته شد. ابتدا، به منظور اطمینان از عدم گسیختگی این مخازن تحت فشار داخلی، فشارهیدرواستاتیک 200 بار به آن‌ها اعمال شد و میزان شاخص شکست این مخازن با استفاده از معیار سای - هیل مورد بررسی قرار گرفت. سپس، جهت ارزیابی رفتار مخازن تحت بار انفجاری خارجی، مدل کانوپ مورد استفاده قرار گرفت. برای این منظور، از ماده تری‌نیتروتولوئن در دو نقطه انفجاری (نزدیک و دور) و سه مقدار خرج انفجار مختلف استفاده شد. در شبیه‌سازی انفجار، مقدار آسیب وارد به ناحیه فلزی و کامپوزیتی مخازن به ترتیب با استفاده از معیار جانسون - کوک و هاشین مورد بررسی قرار گرفت. نتایج حاصل از این پژوهش نشان می‌دهد، مخزن نوع چهارم نسبت به مخازن دیگر بیشترین استحکام در برابر فشار هیدرواستاتیکی داخلی را دارد و می‌تواند تا فشار 610 بار را تحمل کند. بعلاوه، مخزن نوع سوم بالاترین ایمنی را در مقابل موج انفجار خارجی دارد. مقایسه نتایج مربوط به مخازن کامپوزیتی نوع دوم تا چهارم نشان می‌دهد، وجود آستر فولادی در زیر لایه کامپوزیتی تأثیر بسزایی در استحکام مخزن در مقابل ضربه یا انفجار دارد. از نتایج مهم دیگر بدست آمده این است که مخزن نوع اول علیرغم وزن بالا مقاومت خوبی در مقابل فشار داخلی و همچنین موج انفجار دارد.

چکیده [English]

In the current research, the behavior of the first to fourth types of compressed natural gas tanks of the vehicle under internal pressure and the external explosive load was investigated in the ABAQUS finite element software. At first, the hydrostatic pressure of about 200 bar was applied to ensure that these tanks do not fail under internal pressure, and the failure index of these tanks was evaluated using the Tsai-Hill criterion. Then, the CONWEP model was used to investigate the behavior of tanks under external explosive load. For this purpose, Trinitrotoluene material was applied in two explosion points (near and far) and three different explosion charge values. In the explosion simulation, the amount of damage to the metal and composite parts of the tanks was evaluated using the Johnson-Cook and Hashin criteria, respectively. The results of this research show that the fourth type of tank has the highest strength against internal hydrostatic pressure compared to other tanks and can withstand up to 610 bar pressure. In addition, the third type of tank has the highest safety against external explosion waves. A comparison of the results related to the second to fourth type composite tanks shows that the presence of steel liner under the composite layer has a significant effect on the strength of the tank against impact or explosion. Another important result obtained is that the first type of tank despite the high weight has good resistance to internal pressure as well as an explosive wave.
