properties for the mounts and their placement could be
selected. It is important to avoid a resonance between
the exhaust system natural frequencies and the excitation
frequencies. The finite element analysis provides displacements
of the system due to thermal loads and ship
motions, which helps in the selection of the proper
expansion joints and allows easy calculation of loads and
stresses on anchors, mounting points and components.
This avoids unacceptable forces or torques on the
expansion joints and other sensitive components. The
proper mount stiffness can also be selected using
existing software.
