DYNAMIC CHARACTERISTICS ANALYSIS OF AN ESCALATOR USING THE COMPUTATIONAL DYNAMICS PROGRAM

摘要

Predicting dynamic characteristics of an escalator by means of the computational dynamic analysis is a meaningful subject, and has not been thoroughly investigated before. The general purposed kinematic and dynamic analysis program, DADS which has been shown to be effective in the dynamic analysis of multi-body, is utilized to analyze the interaction of the escalator to be more than 900 independent degree-of-freedom. Thousands of friction contact elements are applied to correctly simulate impact, permanent contact and temporary contact of rollers and the handrail. The presented model is experimentally verified to substantiate the accuracy and efficacy.
