MAN B&W 17.05 Guide Force Moments �� Fig. 17.05.01: H�type and X�type guide force moments The so�called guide force moments are caused by the transverse reaction forces acting on the crossheads due to the connecting rod/cranskahft mechan<strong>is</strong>m. These moments may excite engine vibrations, moving the engine top athwartships and causing a rocking (excited by H�moment) or tw<strong>is</strong>ting (excited by X�moment) movement of the engine as illustrated in the above figure. The guide force moments corresponding to the MCR rating (L ) are stated in Table 7.07.0 . Top bracing The guide force moments are harmless except when resonance vibrations occur in the engine/ double bottom system. As th<strong>is</strong> system <strong>is</strong> very difficult to calculate with the necessary accuracy MAN Diesel strongly recommend, as standard, that top bracing <strong>is</strong> installed between the engine’s upper platform brackets and the casing side. The vibration level on the engine when installed in the vessel must comply with MAN Diesel vibration units as stated in Fig. 7.05.02. �� Page of 3 �� MAN B&W MC/MC�C, ME/ME-B/ME�C/ME�GI engines 198 42 23�3.3 MAN Diesel �� 178 06 81�6.3 We recommend using the hydraulic top bracing which allow adjustment to the loading conditions of the ship. Mechanical top bracings with stiff connections are <strong>available</strong> on request. With both types of top bracing above�mentioned natural frequency will increase to a level where resonance will occur above the normal engine speed. Details of the top bracings are shown in Chapter 05. Definition of Guide Force Moments Over the years it has been d<strong>is</strong>cussed how to define the guide force moments. Especially now that complete FEM�models are made to predict hull/ engine interaction, the propeller definition of these moments has become increasingly important. H�type Guide Force Moment (M H ) Each cylinder unit produces a force couple cons<strong>is</strong>ting of: . A force at crankshaft level. 2. Another force at crosshead guide level. The position of the force changes over one revolution as the guide shoe reciprocates on the guide.
