Steel Band Loading Technology and Its Finite Element Analysis of Fuselage Force Simulation

摘要: 大型运输机机身直径大、蒙皮相对薄弱，集中载荷容易对其造成局部破坏。为了解决类似结构的加载问题，本研究阐述了钢带加载技术的结构形式、材料选择、胶粘剂选择及粘贴工艺，并通过有限元分析的方法模拟了机身的钢带加载。结果表明：钢带加载技术能够较好地模拟机身受力，且具有自身结构形式简单、成本低、体积小、使用灵活等众多优点。

Abstract: Large transport aircraft body cover has large diameter and thin skin, and is easy to be damaged by concentrated load. To study and solve the problem, the steel band loading technology is investigated from the perspectives of the steel band loading structure, selection of materials, adhesive selection and paste process. The steel band loading of fuselage is simulated by finite element analysis. The result shows that the steel band loading technology can simulate the force loaded on the fuselage effectively, and the technology is simple structured, inexpensive, small in volume, and flexible, therefore, the steel band loading technology is a technique worthy of further research.
