Structure-borne sound power and source characterization in multi-point-connected systems, part 2: About mobility functions and free velocities

As an aid to the control of structure-borne sound the characterization of a machine as a structure-borne sound source would constitute a useful design tool. Towards this goal, a formulation based upon a machine's ability to d eliver power has been proposed by Mondot and Petersson [1]. To progress the ir proposal, this paper examines in an ordered manner those physical parame ters which determine the vibrational power in a system involving multiple c onnections. The structural characteristics of typical machine and floor mou nt conditions are considered by examination of mobility relationships whils t the machine excitation (or source activity) characteristics are considere d via free velocity relationships, (C) 1999 Academic Press.
