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.

高层公寓绳索电梯运行噪声与振动的特点及实际条件研究

电梯是高层公寓中非常重要的设备。电梯发出的噪音给居民带来不便。然而，目前尚无关于电梯噪声的法律法规，更没有明确的方法对电梯噪声进行测量和评价。针对这些问题，首先要掌握电梯运行过程中产生的噪声和振动的特性。在本研究中，根据楼层数和房间类型对高层公寓中钢丝绳式电梯运行时产生的噪声和振动进行划分，并同时测量噪声和振动，了解噪声和振动的特性。根据实验条件确定了相关系数。结果发现，电梯噪声主要由125 Hz ~ 500 Hz频段的分量组成，且与125 Hz ~ 500 Hz频段振动的相关性也很显著。对于顶层，在0.8水平上证实相关系数非常高。
