飞机复材结构几何-物理装配状态对服役性能的影响
Influence of assembly geometric and physical properties of aircraft composite structure on service performance
摘要
Abstract
Due to the weak rigidity and large manufacturing deviations of thin-walled composite structural compo-nents,geometric deviations,excessive internal stresses,and assembly damage are prone to occur during assembly.The current assembly modes mostly consider the satisfaction of geometric accuracy,and pay less attention to the dis-tribution of internal stresses and damages between components.The highly uncertain assembly stresses and dam-ages packaged into service will affect structural stability directly.Firstly,the types and characteristics of assembly ge-ometry deviations,the generation of internal stresses in assembly,and the formation mechanism of assembly damage were analyzed.Then,a correlation model between assembly geometry physics service assembly performance was proposed,demonstrating the bidirectional relationship between assembly geometry and physical performance on ser-vice performance.Secondly,the dynamic changes of initial assembly geometry deviation,internal stress,and dam-age state during service,as well as their impact on mechanical properties such as aircraft structural strength and fa-tigue life were analyzed,and basic theoretical guidance for the correlation analysis between assembly process and service performance indicators would be provided.Finally,key technologies such as assembly geometry and physical performance modeling,assembly service performance prediction,virtual simulation testing of assembly performance and service performance,and reverse engineering of assembly process parameters for service performance assur-ance were analyzed.Moreover,how to construct an assembly process model transformation for service performance assurance was discussed.关键词
