Abstract

Abstract:

Aiming to learn the loading formality of a four-wheel-juxtaposed landing gear of large airplane, loading model of its welded main wheel axle was established during the landing process. Finite element analysis was done about the force distribution on the welded main wheel axle by taking plane EL-76 as example. Results show that equivalent stress is greatest in two welding seams, where fracture may take place with highest ratio. The first landed wheel suffers cyclical loading, which may lead to fatigue fracture of the axle.

Key words: landing gear, wheel axle, welding, loading model, stress analysis

摘要：

针对大飞机上常用的四轮并列式起落架,给出了飞机在着陆准稳态阶段,其起落架焊接主起轮轴的受载数学模型。以伊尔-76飞机为研究对象,采用有限元分析软件ANSYS,模拟了其机轮着陆过程中焊接主起轮轴受力状况。结果表明,主起轮轴上两道焊缝处应力最大,断裂几率最高,最先着陆机轮的轴颈处由于受到循环载荷作用,易发生疲劳断裂。
