AB - <p class="MsoNormal" style="text-indent:35.3pt;line-height:normal;"> <span lang="en-us" xml:lang="en-us">Excitation energy of rotating machinery propagates through the
connection paths resulting in vibration responses at the structures such as
machine foundations. Accurate prediction of these vibration responses at a
point of a complex structure, where the operational behavior cannot be measured
directly, is an important engineering problem for design optimization,
component selection and condition monitoring. The main step of the prediction is
to identify the internal forces acting on the connection paths of the
machinery. At the circumstances where direct measurement is impossible or
impractical due to physical constraints, an indirect approach is to identify
the exciting forces based on multiplication of an inverted frequency response
functions (FRFs) matrix and a vector of vibration responses measured at the
points where the exciting forces are transmitted through. </span> <span lang="en-us" xml:lang="en-us"> The aim of this paper is to
present matrix inversion method to identify the exciting internal forces and
hence, predict the vibration response at the point of interest. <i> </i> </span> </p> <p> <i> </i> </p> <i> </i>
