| 摘 要： | 飞机装配制孔过程中施加一定的压紧力可以有效控制贴合面间隙,而飞机大部件对接自动化制孔,只能采用单向压紧的方法。本文首先分析了单向压紧力对毛刺的影响,并讨论了压紧力分析的3种分析方法,然后以某飞机中机身和中后机身对接处的典型位置为实例,应用有限元方法分析了贴合面间隙随压紧力变化情况,最后给出合理的压紧力推荐值。

| Abstract: | Interfacial clearance could be controlled effectually through putting pressure on the skin of aircraft.when drilling a hole on the skin of airplane,It can only use one-side pressure.The effect of pressure on the interface is analyzed,and then three methods for pressure analysis are discussed.A typical docking location of middle-fuselage and middle-after fuselage sections is taken for example.The relationship between interfacial clearance and pressure is analyzed by using finite element method(FEM).Finally,a rational value of pressure is presented. |
