NON-INVASIVE VIBRO-ACOUSTIC ANALYSIS

摘要

A system provides an in situ or non-invasive vibro-acosutic (VA) analysis of an arbitrary complex vibrating structure. The major advantages of this system are that: (1) it allows for an identification of the VA modes that are directly responsible for structural vibration and sound radiation; (2) it enables one to acquire a quantitative description of contributions from individual VA modes that are responsible for resultant structural vibration and sound radiation; and (3) it is non-invasive so that one can conduct an in
