基于EVA的电梯振动检测与分析

Based on EVA Elevators Vibration Detection and Analysis

以某公司电梯为研究对象，利用EVA电梯振动分析系统将运行数据通过振动分析软件处理，获得电梯上下行Z方向位移及3轴的加速度时间关系曲线、电梯噪声时间关系曲线，并采用ISO滤波和快速傅立叶转换获得人体对运行感受的直观图像显示以及电梯振动数据的振幅和频率信息。

This paper lift for a company study, using EVA elevator vibration analysis system will run through vibration data analysis software processing, access to the lift line from top to bottom Z direction displacement and 3-axis acceleration time curve, the lift curve of the time noise, filtering and the adoption of ISO and fast Fourier transform feelings are running the human visual image display and lift the vibration amplitude and frequency of data information.
