Horizontal vibrations on top of engine are caused
by the guide force moments. For 4�7 cylinder
engines the H�moment <strong>is</strong> the major excitation
source and for larger cylinder numbers an
X�moment <strong>is</strong> the major excitation source.
For engines with vibrations excited by an
X�moment, bracing at the centre of the engine are
of only minor importance.
Top bracing should only be installed on one side,
either the exhaust side or the manoeuvring side.
If top bracing has to be installed on manoeuvring
side, please contact MAN Diesel.
If the minimum built�in length can not be fulfilled,
please contact MAN Diesel or our local representative.
The complete arrangement to be delivered by the
shipyard.
