ACOUSTIC VIBRATION ANALYSIS METHOD AND APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an acoustic vibration analysis method where measurement work time is short and calculation accuracy is high. SOLUTION: A structure to be subjected to acoustic and/or vibration analysis is modeled as a combination body of a plurality of subsystems, and acoustics and/or vibration at the response point of an arbitrary subsystem to the input point of an arbitrary subsystem are evaluated by the energy balance of each subsystem in the acoustic vibration analysis method. A subsystem at least at an input point A and a subsystem B at a response point are directly coupled for modelling.
