Estimation of parameters affecting ride comfort in elevator

Abstract

Among the demands for energy saving and high efficiency improvement of equipment, comfort is required as added value. Vibration and noise during elevator travel propagate into the car, which induces a feeling of ear blockage and car shaking. As a result, the ride comfort, which is one of the comforts, is reduced. In this paper we focus on the ride comfort of the elevator. In order to evaluate the ride comfort of the elevator, an elevator that can change the rated speed and control acceleration when going up and down is used. By using this elevator to acquire data, we combine human subjective evaluation and objective evaluation by physical quantity to extract parameters that affect ride comfort. As a method, each index is extracted by multivariate analysis of sensory evaluation data and physical evaluation data, and they are subjected to multiple regression analysis to make association. As a result, the parameter to be affected is acceleration, and in particular, it is effective to reduce the longitudinal acceleration of the human being for riding comfort. Therefore, it can be expected to devise a method to realize a comfortable ride comfort with an inexpensive system by limiting the countermeasure points of the elevator.
