Composites Design Cascade Escalator Glass Fiber Reinforced

With lower energy consumption and conserve resources has become increasingly higher, lightweight Mechanical structures are more and more attention in the current spatial structure and has been widely applied in areas such as automotive lightweight technology. Elevator as one power-hungry modern society, how to reduce energy consumption continued operation of escalators, is needed to solve the problem. In an escalator, due to the large number of rungs, and often moving parts, so in a cascade structure to ensure performance meets the requirements of the premise, to reduce the quality rung for reducing the energy consumption of the escalator, resource saving aluminum and improve economic efficiency is important. In this paper, an elevator company in Jiangsu explore the application of composite materials research project-based, fiber-reinforced composite material according to the characteristics of lightweight, high strength, combined with its own structural characteristics escalator rung, to design a composite escalator steps, and then follow the GB16899-2011 "escalators and moving walkways manufacture and installation of safety norms" requirements, its static and dynamic load test simulation, exploration and research of glass fiber reinforced composite material used on the escalator rung feasibility of lightweight. The main research analysis is as follows:First, the overall die-cast aluminum escalator rung for the study, based on glass fiber reinforced composite lightweight, high strength characteristics, combined with its own structural characteristics escalator rung, to design a composite escalator steps, and then follow the escalator rung national standard static load test requirements, respectively, and its integral aluminum die-casting escalator rung makes a static load test simulation, the two materials rung displacement contour and equivalent stress cloud, and were analyzed.Secondly, according to the national standard escalator cascade dynamic load test requirements, the two materials were rung modal analysis, harmonic analysis and fatigue analysis, the two materials rung first six natural frequencies and mode shapes, displacement response cloud and displacement response curve, fatigue life and fatigue safety factors cloud cloud, and the results were analyzed and compared.Finally, the two materials rung static load and dynamic load test simulation analysis and comparison of results, the glass fiber reinforced composite escalator cascade topology optimization design to static and dynamic load test performance to meet the national standard Cascade escalator requirements, and not less than monolithic aluminum die-casting escalator rung premise static and dynamic load test performance under further reduce its quality.Analysis of this dissertation lightweight high strength fiber-reinforced composite material exploring the application of the escalator rungs provide some reference.
