| 内容記述 | Identifying external forces and contribution rates from input power sources during machine operation is important for analyzing machine and equipment, and dynamic designs. The comparison method between input powers and contribution rates from power sources to a simple structure consisting of two flat plates and a partial car model consisting of four subsystems in machine operation determined by SEA and inverse matrix TPA was proposed by the authors in the past studies, and the validity of this method was shown. However, it is necessary to extend to the sound fields in order to realize utilization of this comparison method. In this paper, the method is validated through numerical analyses, using a finite element method of a simple structure consisting of seven plate structure including one internal sound field. As a result, the SEA vibrational input power is spatial averaged over each subsystem quantitatively agrees with the TPA input power expressed as the product of the force and velocity at the excitation point. The SEA acoustical energy qualitatively agrees with the TPA acoustical energy. Contribution rates from a power source, when applying the new method to make a comparison between the SEA and TPA results, the effectiveness of the method has been verified. | |||||||||
