Location of Interior Impact Source in Randomly Excited Structures.

摘要

A technique for identifying the location of an internal impact source in a randomly excited structure is developed in this paper. It is shown that when an impact source can be modelled as a shot noise random process, a straightforward procedure can be used along with standard testing and measurement procedures to find the impact source. The results of a laboratory experiment are presented; these demonstrate the applicability of the technique. 5 refs., 7 figs.
