Hull lệch kết quả trong Vòng bi động cơ trở thành rỗng Sử dụng số ảnh hưởng đến phản ứng S i, kết nối với biến dạng thân tàu, chúng ta có thể xác định số tiền chuyển tương đối của thân tàu có thể gây ra thứ i mang động cơ để trở thành dỡ. Có hai trường hợp, trong đó, hoặc hỗ trợ đàn hồi (hỗ trợ mùa xuân) hoặc hỗ trợ cứng nhắc (đơn giản) | ClassNK PART B AMENDMENT OF THE GUIDANCE TO THE RULES AND ITS EXPLANATORY NOTES 3 Hull Deflection that results in Engine Bearings Becoming Unloaded Using the reaction influence number Si connecting with hull deformation we can determine the amount of relative displacement of the hull that would cause the ih engine bearing to become unloaded. There are two cases in which either elastic support spring support or rigid support simple support are used as the support condition of the bearings to calculate the reaction influence numbers Cm n . Each case is examined below. AR i 0 - R i s Bi Si . Since unloading of engine bearings due to aftmost bearing in most cases both Sb2 compared with the lower limit. aded No. Hence Sb - Ri Si . 6 Initial condition of engine bearings.

Let Ri be the r i from aft before hull deformation and let Sbi be the relative di position of the aftmost bulkhead of the engine room at whi unloaded after hull deflection then In the case of rigid support Figure shows how to de deflection. In cases where corresponding to the given off of the support poi stiffness spring is considered load as sho engine third ess is to be in the state before hull tion bearing reaction Ri earing and the displacement 1 a . However if the effect of the displaced downward slightly by the ge in the bearing reaction Ri for each b Elastic support Ri does not change even if the effect of the stiffness spring is considered each support point after loading is expressed with the stiffness K constant of t using the following equation In the discussion below we examine the change in bearing reaction when the hull deflects from the initial condition shown in Figure b due to an increase of draught. Figure shows the change in the support point contact point with the shaft
