차량진동에 대한 노출가스관의 방진 시스템 개발을 위한 실험적 연구

In this paper, aerials gas pipeline vibrations due to the passing of vehicles have been measured, and peak values and characteristics of vibration were analyzed. In order to develop isolation system for gas pipeline, six cases with various support condition and hanging method were tested. The hanger used instead of wore rope isolated almost all vibrations transmitted from main beam. In the results of test, we could decrease response of vibration velocity from 49 % to 56 % and response of vertical vibration acceleration from 49 % to 60 %, because hanger instead of wire rope was used and rubber pads instead of wooden shield plates at support positions for Proofing horizontal vibration were used.
