BẢNG TRỊ CÁNH TAY ĐÒN ỔN ĐỊNH HÌNH DÁNG

Chiều dài tàu 21.42 m

Chiều rộng tàu 3.426 m

Chiều cao mạn 1.65 m

Mớn nước 0.64 m

Hình vẽ cách xác định cánh tay đòn ổn đinh GZ theo KN

* Tính GZ theo KN:Để tính toán tay đòn ổn định tại những góc nghiêng khác nhau của tàu trong một trạng thái, chiều cao ổn định tĩnh GZ được xác định từ:

GZ = KN – a x sin

GGo= ∑ Mh / Disp

∑ Mh : momen do ảnh hưởng mặt thoáng hàng lỏng

DISP : Lượng chiếm nước

Trong đó:

KN = Cách tay đòn ổn định hình dáng

CGZ = Cao độ trọng tâm tàu

= Góc nghiêng

Tay đòn ổn định GZ được tính toán phù hợp với công thức phía trên và vẽ biểu đồ theo góc nghiêng ngang.

* Tính GZ theo MS:GZ = MS + GM x sin MS: Cánh tay đòn ổn định dư

GM: Chiều cao tam nghiêng

Góc nghiêng.
