تاثیر پریود امواج بر روی اتصالات سازه های شناور به هم پیوسته

چکید ه

در این مقاله اثر پریود موج در پین اتصالات اسکله های شناور مدولار بررسی شده است. اسکله به صورت سازه ای با بدنه های صلب و اتصالات مفصلی- صلب مدل گردیده است. سه پانتون با ابعاد  1.8*7*20 متر و عمق آب نیز با توجه به مشخصات کشتی طرح 7 مترو پریود موج غالب 5 ثانیه در نظر گرفته شده است. امواج بر خوردی در راستای طولی سازه شناور انجام شده است. معادلات امواج، استوکس مرتبه 5 لحاظ شده است. فرایند تحقیق با دو نرم افزار آباکوس و استارسی سی ام پلاس انجام شده است و با توجه به عملکرد نرم افزار از روش تحلیل دینامیکی کامل استفاده شده است. با کوپل این دو نرم افزار، تنش در پین اتصالات بدست آمده است. نتایج حاصل نشان می دهد که با افزایش دوره تناوبی به ثانیه، شدت تنش وارده به پین اتصال افزایش یافته است. این نتایج حاکی از آن است که طراحی هر سیستم سازه ای شناور نیازمند به انتخاب معیار و ملاک مناسب و منطقی است. بنابراین در مناطق با پریود موج بالاتر از پریود موج غالب، انتخاب چنین سازه ای به ندوت رخ می دهد.

Period waves impact on the floating structures interlocking connections

Abstract

In this paper the effect of modular floating dock connectors pin wave period studied. Handles for rigid body structure with a rigid model is Mfsly- connections. Tuesday Pantone size 1.8 * 7 * 20 m and depth profile with respect to ship the 7 subway dominant wave period of 5 seconds is considered. Eat in longitudinal direction of the waves on the floating structures. Wave equation, Stokes is in the order of 5. ABAQUS software with the research process and Astarsy thirtieth Plus has been done with regard to the application of the full dynamic analysis method is used. By coupling these two software, tension bolt connections have been obtained. The results show that by increasing the Period in seconds, greatly increased the stress to the pin connection. These results suggest that the design of any system of floating structures need to choose the appropriate and logical criteria. Therefore, in areas with a dominant wave period, wave period above, the choice of such a structure rarely occurs
