実稼働 TPA における応答点振動低減手法についての一考察

Abstract

In this study, we considered effective countermeasures for reduction of the response point vibration utilizing analytical result of operational transfer path analysis (OTPA) through several vibration tests. OTPA informs us each contribution of the reference point to the response point quantitatively. Conducting intensive countermeasure to the obtained high contributing part is appropriate way for the reduction of the response point vibration in general. However, when the highest contribution of a reference point is much larger than the response point vibration itself, the countermeasure to the highest reference point did not reduce the response point vibration significantly in the vibration test. On the other hand, the countermeasure to the response point could reduce the vibration well in this situation. From these analytical and experimental results, the suitable countermeasure method was proposed according to the highest contribution level.
