Abstract
A new simulator for estimating escalator dynamics motion has been developed. It reduces the experimental cost and time compared with a conventional experimental-based testing method. It uses a commercial multibody dynamics software applied to the analysis of the motion of an escalators' component. And it can not only simulate the motion of each component, but also solve determine the result reaction forces. Two examples are presented to demonstrate the efficiency of the simulator. In first one, the rotating motion of steps is simulated in order to determine the reaction force on the structure. This simulation ensures that the structural strength of the escalator can withstand the reaction force. In second one, the contact reaction force between the chains and gear is analyzed. Then, to reduce noise, the chain-and-gear structure can be re-designed to reduce the reaction force. These examples show the importance of the proposed simulation.
