轻型飞机翼肋支柱端与端部配件的配合强度实验
Experimental Study on the Fit Strength of Aircraft Wing Rib Pillar End and End Accessories
摘要
Abstract
During the flight of an aircraft,the wings are mainly supported by the wing ribs of the aircraft,at the same time,during flight,when the aircraft is subjected to strong airflow resistance,wing ribs can help alleviate the tension and airflow compression that the aircraft is subjected too.Therefore,optimizing the design of wing pillars can greatly improve the pressure borne by aircraft during flight,thereby improving flight safety.The most important part of wing rib pillar design is the connection and coordination between the pillar end and end fittings,which are connected by spot welding.Two different types of pillar end connection are designed.In the experiment A,the aluminum pillar end is directly fix on the iron plate through spot welding;in the experiment B,a section of the pillar is covered with an iron sleeve and it is fixed on the iron plate through spot welding.The load-bearing capacity and lateral bending deflection are compared by experimental analysis.The results show that the design scheme of experiment A can better withstand pressure,has higher safety,and is more suitable for future research on the design of aircraft wing pillars.关键词
