机体变形和压力冲击载荷下飞机液压导管强度分析
Strength Analysis of Aircraft Hydraulic Pipe Under the Coupling of Body Deformation and Pressure Impact
摘要
Abstract
The aircraft hydraulic pipe system is characterized by "scattered,messy,long and miscellaneous".It is one of the most common failures of aircraft.With the high pressure of aircraft hydraulic system,the strength analysis of hydraulic pipe is more important.Under the coupling of two loads of body deformation and pressure impact,a certain oil return pipe of a certain aircraft wing is introduced,through the comparison and analysis of the theoretical calculation of stress,simulation stress and experimental stress,the correctness of the analysis and simulation method of the strength analysis and the conclusion that the body deformation load has little influence on the strength of the catheter are obtained.Finally,the comprehensive evaluation of the three methods for the analysis of the strength of the ducts is made.The research contents have certain engineering practice and theoretical guidance significance for the strength analysis of aircraft hydraulic pipe.关键词
