Vibration Evaluation Focusing on Response at Specific Position of the Piping System

Abstract

The purpose of this study is to evaluate the vibration response of the piping system at the early stage of design more rationally and efficiently than before. The piping system has the in-phase and antiphase vibration modes, and if conventional method using the participation factor is applied, the vibration may be underestimated. Therefore, a new evaluation method using the partial participation factor focused on specific part is applied. By using this method, supported positions of the piping system with dampers are determined. Then, the vibration response calculation was carried out by the conventional method and the proposed method, and the effect was compared.
