Abstract

An Elevator is a very important equipment in high-rise apartments. The noise generated by an elevator is causing inconvenience to residents. However, there are no laws and regulations on elevator noise, and moreover it is not clear how to measure and evaluate elevator noise. For these problems, the first priority should be given to grasping the characteristics of noise and vibration generated during elevator operation. In this study, noise and vibration generated when operating a rope-type elevator in a high-rise apartment are divided according to the number of floors and the type of room, and the noise and vibration are simultaneously measured to understand the characteristics of noise and vibration. The correlation coefficient according to the experimental conditions was determined. As a result, it was found that elevator noise was mainly composed of components in the 125 Hz to 500 Hz band, and the correlation with vibration in the 125 Hz to 500 Hz band was also significant. For the top layer, it was confirmed that the correlation coefficient was very high at 0.8 level.

승강기는 고층아파트에서 매우 중요한 설비기기이다. 이러한 승강기가 운행할 때 발생하는 소음은 거주민에게 불편함을 주고 있다. 하지만 승강기 소음에 대한 법규 및 규정은 없는 실정이며, 승강기 소음을 측정하고 평가하는 방법 또한 명확하지 않다. 이러한 문제는 승강기 운행 시 발생하는 소음과 진동의 특성 파악이 우선 시 되어야 한다. 본 연구에서는 고층아파트 로프식 승강기 운행 시 발생하는 소음과 진동을 측정 층수와 측정 실의 종류에 따라 나누어 측정 하였다. 소음과 진동의 동시 측정을 진행하여 소음과 진동의 특성을 파악하고, 상관성 분석을 통해 각 실험 조건에 따른 상관계수를 파악 하였다. 그 결과 승강기 소음은 125 Hz ~ 500 Hz 대역의 성분이 주요하고, 125 Hz ~ 500Hz 대역에서 진동과의 상관성 또한 유의미한 것으로 파악 되었다. 최상층의 경우 상관계수가 0.8 수준으로 매우 높음을 확인 하였다.
