Structural design and mechanical performance evaluations of flexible and lightweight belt by CFRP

摘要

This research presents the structural design and mechanical performance evaluation results of a lightweight belt for high-rise elevators. Weight reduction of elevator components is indispensable in developing ultra-high-rise elevators. In this study, the structural design and performance evaluation of high-rise elevator ropes were carried out. The weight of the newly designed Carbon Fiber Reinforced Plastic (CFRP) belt was reduced by 30% compared with the original steel wire rope. The structural analysis results of the CFRP belt showed that the design criteria were met on the design load condition of the belt. Also, mechanical tests were executed to verify the mechanical characteristics of the newly developed belt, with the results showing that the belt had sufficient structural performance compared with conventional steel wire rope.
