Purpose

The comfort of lift passengers has a significant effect on their general health condition as well as stress levels during travel. This study reports the results of vibration measurements taken during travel in a passenger lift.

Methods

Vibration signals were analyzed by the empirical mode decomposition method and the Hilbert transform.

Results

Selected modes from the Hilbert spectral analysis were compared with the resonance frequencies of human body organs (range 20–90 Hz) as well as with the resonance frequencies of lift components.

Conclusion

The use of Hilbert spectral analysis enables the isolation of individual signal components and the determination of the dominant frequency in the signal. This, in turn, allows for the isolation of raw vibration frequencies from the signal that are particularly significant for passenger comfort assessment (resonance frequencies of human body organs) and analysis of their occurrence.

通过希尔伯特-黄变换评估电梯乘客的舒适度

目的

升降机乘客的舒适度对其总体健康状况以及旅行过程中的压力水平有重要影响。这项研究报告了乘搭乘客电梯期间进行振动测量的结果。

方法

通过经验模态分解法和希尔伯特变换对振动信号进行了分析。

结果

从希尔伯特频谱分析中选择的模式与人体器官的共振频率（范围为20–90 Hz）以及举升部件的共振频率进行了比较。

结论

希尔伯特频谱分析的使用可以隔离单个信号分量并确定信号中的主频。反过来，这允许从信号中分离出原始振动频率，这对于乘客舒适度评估（人体器官的共振频率）及其发生的分析特别重要。
