Abstract

Nowadays, elevators are installed for most of buildings and they are familiar with everyone in modern life. Thus, the elevators are required smoother and quieter. However, elevator manufacturing factories have no method and equipment to measure vibration in elevators. This paper introduces a method using an accelerometer and Fast Fourier Transform (FFT) to recognize vibration spectrum. This spectrum will be compared with standard one built by the manufacturer. In this paper, the standard spectrum of well-known elevator manufacturers such as Otis, Schindler etc. will be introduced for reference of Vietnamese elevator manufacturer.
