MAN B&W 17.05 �� Fig.17.05.02: Vibration limits �� Page 2 of 3 MAN B&W MC/MC�C, ME/ME-B/ME�C/ME�GI engines 198 42 23�3.3 MAN Diesel �� 078 81 27-6.0
MAN B&W 17.05 As the deflection shape for the H�type <strong>is</strong> equal for each cylinder the N th order H�type guide force moment for an N�cylinder engine with regular firing order <strong>is</strong>: N x M H(one cylinder) For modelling purposes the size of the forces in the force couple <strong>is</strong>: Force = M H /L [kN] where L <strong>is</strong> the d<strong>is</strong>tance between crankshaft level and the middle position of the crosshead guide (i.e. the length of the connecting rod.) As the interaction between engine and hull <strong>is</strong> at the engine seating and the top bracing positions, th<strong>is</strong> force couple may alternatively be applied in those positions with a vertical d<strong>is</strong>tance of (L Z ). Then the force can be calculated as: Force Z = M H /L Z [kN] Any other vertical d<strong>is</strong>tance may be applied, so as to accomodate the actual hull (FEM) model. The force couple may be d<strong>is</strong>tributed at any number of points in the longitudinal direction. A reasonable way of dividing the couple <strong>is</strong> by the number of top bracing and then applying the forces at those points. Force Z, one point = Force Z, total /N top bracing, total [kN] X�type Guide Force Moment (M X ) The X�type guide force moment <strong>is</strong> calculated based on the same force couple as described above. However as the deflection shape <strong>is</strong> tw<strong>is</strong>ting the engine each cylinder unit does not contribute with an equal amount. The centre units do not contribute very much whereas the units at each end contributes much. A so�called ‘Bi�moment’ can be calculated (Fig. 17.05.01): ‘Bi�moment’ = Σ [force�couple(cyl.X) x d<strong>is</strong>tX] in kNm 2 Page of The X�type guide force moment <strong>is</strong> then defined as: M X = ‘Bi�Moment’/L kNm For modelling purpose the size of the four (4) forces can be calculated: Force = M X /L X [kN] where: L X <strong>is</strong> the horizontal length between ‘force points’ Similar to the situation for the H�type guide force moment, the forces may be applied in positions suitable for the FEM model of the hull. Thus the forces may be referred to another vertical level L Z above crankshaft centre line. These forces can be calculated as follows: Force = Z, one point M _____ x L x L x L [kN] In order to calculate the forces it <strong>is</strong> necessary to know the lengths of the connecting rods = L, which are: Engine Type L in mm K108ME�C6 ,400 K98ME6/7 ,220 K98ME�C6/7 ,090 S90ME�C7/8 ,270 K90ME9 , 20 K90ME-C9 ,120 K90ME�C6 ,159 S80ME�C9 ,450 S80ME�C7/8 ,280 K80ME�C9 2,975 K80ME�C6 2,920 S70ME-C7/8 2,870 S70ME�GI7/8 2,870 Engine Type L in mm L70ME�C7/8 2,660 S65ME�C8 2,7 0 S65ME�GI8 2,7 0 S60ME�C7/8 2,460 S60ME�GI7/8 2,460 L60ME�C7/8 2,280 S50ME�C7/8 2,050 S50ME-B9 2,114 S50ME-B8 2,050 S40ME-B9 1,770 S 5ME-B9 1,550 MAN B&W ME/ME-B/ME�C/ME�GI engines 198 45 17�0.5 MAN Diesel
