Abstract
Over the period of use, elevators need to be updated to ensure their functionality, safety, an extension of service life, and passenger comfort. The necessary modernization process replaces essential components for the full functioning of the elevator. This work quantitatively evaluates the gain in the degree of comfort of travel concerning vibration and over-acceleration caused by displacement to check the improvements. Measurements were carried out on non-modernized elevators and after being fully modernized in the same building. A seat pad device with an accelerometer and a VI-400Pro device was used to measure the vibration transmitted to the human body, standardized inside the cabin during elevator journeys. Subsequently, the data were processed in the MATLAB R2012 software. The measurements are carried out by the methodology indicated by ISO 18738:2003, comparing the results thus obtained with the values referring to passenger comfort following ISO 2631-1:1997 and literature. The analysis of the results obtained from the data processing shows that considering the vibration, all trips are considered comfortable, but there is a decrease in vibration for the modernized cases. Regarding jerk, all values obtained from the old elevators are unacceptable, while the modern ones are in the acceptable range.
