Horizontal distance between top bracing fix point
and cyl. 1
Horizontal vibrations on top of engine are caused
by the guide force moments. For 47 cylinder en-
gines the Hmoment is the major excitation source
and for larger cylinder numbers an Xmoment is
the major excitation source.
For engines with vibrations excited by an
Xmoment, 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 & Turbo.
If the minimum builtin length can not be fulfilled,
please contact MAN Diesel & Turbo or our local
representative.
The complete arrangement to be delivered by the
shipyard.
