چکیده

در این مقاله به بررسی دریامانی سه نوع بدنه مختلف می پردازیم. همانطور که می دانیم دریامانی قابلیت یک شناور یا سازه دریایی جهت شناوری مطلوب به حساب می آید بطوری که اگر یک سازه شناور یا یک شناور، دریامانی خوبی داشته باشد، قادر است در شرایط دریای خراب نیز عملکرد قابل قبولی را دارا باشد. با بررسی عددی حرکات جابجایی قائم[1] و غلتش طولی[2] سه بدنه ویگلی، سری 60 و شناور DDG 51  [3]در شرایط موج منظم مقابل و معتبر سازی نتایج عددی بصورت مقایسه با نتایج تجربی، به پیش بینی دریامانی شناور ناوشکن در اثر تغییر نسبت های ابعادی در نرم افزار مکسرف[4] پرداخته ایم. لازم به ذکر است که حرکات کشتی تابع شکل و اندازه بدنه می باشد اما از نتایج حاصل از این مقاله نمی توان در موارد مشابه استفاده نمود.

چکیده [English]

In this article we have discussed seakeeping different body types. As we know seakeeping ability of a vessel or offshore structure to the desired buoyancy is such that if a vessel or floating structures, seakeeping good, bad sea conditions can also have acceptable performance. Numerical Investigation movements with heave and pitch of three type hull of Wigley, Series 60 and DDG 51 floating in front of the regular wave and validation of numerical results are compared with experimental results to predict seakeeping floating ship in effect Maxsurf Ratios software deals have. It should be noted that the shape and size of ship movements of the body, but the results of this study cannot be used in similar cases.
