Influence of Corrosion Thinning on Strength and Rigidity of Escalator Truss

Abstract

Corrosion thinning is one of the main failures of the escalators. In this paper, the influence of corrosion thinning on strength and rigidity of three typical escalator trusses are analyzed by finite element calculation. The calculation results show that the corrosion thinning has little effect on the strength, but has great effect on the rigidity of escalator trusses. Therefore, in the escalator design, it is necessary pay more attention on improving the rigidity of the truss, so as to avoid the inflection of truss exceeding the standard requirement.
