Abstract
Perforated discs have many applications in different parts of industry. By making such disks of functionally graded materials, more capabilities can be obtained from them. Vibration analysis of these kinds of disks can help us make them more efficient. In this paper, modeling and evaluation of disk vibration of functionally graded materials with regard to thickness were carried out using Abaqus software. Since no certain element has been defined regarding functionally graded materials for the design and analysis of a particular element in Abaqus software, molding of such materials has been used in this application. In order to verify the results, the results obtained from ABAQUS analysis have been compared with those available in the literature. The obtained results show that by defining more layers with regard to changes in properties, the obtained results approach the exact solutions.
دیسک‌های سوراخ‌دار در بخش‌های مختلف صنعت کاربرد‌های فروان دارند. با ساخت این دیسک‌ها از جنس مواد مدرج تابعی، قابلیت های بیشتری از آن‌ها می‌توان به‌دست آورد. تحلیل ارتعاشی این نوع دیسک می‌تواند در ساخت هر‌چه کارآمد‌تر آن به ما کمک کند. در این مقاله، مدل‌سازی و بررسی ارتعاشات آزاد دیسک از جنس مواد مدرج تابعی در راستای ضخامت، با نرم‌افزار آباکوس انجام شده‌است. از آن‌جا که در نرم‌افزار آباکوس در زمینه طراحی و تحلیل مواد مدرج تابعی المان خاصی تعریف نشده است، مدل سازی این مواد در این نرم افزار انجام شده‌است. به منظور صحت‌سنجی، نتایج تحلیل آباکوس با نتایج موجود در مقالات مقایسه شده است. نتایج به‌دست آمده نشان می‌دهد که با تعریف لایه‌های بیشتر در راستای تغییرات خواص، نتایج به‌دست‌آمده به جواب‌های دقیق نزدیک‌‌تر می‌شود.
