摘要
针对某型飞机机身前段和中段对接时,对接框机身外形阶差连续几架飞机超出设计技术条件规定的问题,从零件制造、装配型架卡板外形、装配应力三方面分析产生故障的原因,并采取相应的控制措施,使部件装配时外形符合要求,最终解决了机身对接时发生的阶差超差问题。
To solve the problem that during the integration of fuselage forward section and middle section, the step of fuselage profile is out of tolerance exceeding design technical conditions for several consecutive shipsets, this article analyzes the reasons for this non-conformance from three aspects of part manufacturing, dimension of assembly jig cardboard, and assembly stress, and takes the corresponding control measures so as to make part sizes conform to requirements in assembly, thus solving the problem of step out-oftolerance during fuselage integration.
