Metodi per migliorare le scale mobili = Methods for improving escalators

Abstract

This paper presents several methods to search for improvements in escalator design. Escalators were invented more than a century ago. During this time several features have been developed although most of them have not shown any clear advantage over the conventional device. This mechanism is becoming a ¿commodity¿ product. CITEF is using tools to simulate and to analyze the static, kinematic and dynamic behaviour of this multibody system. We have used MATLAB, CATIA and SIMPACK software. In addition, a life prediction model based on dynamic results has been developed
