某型飞机机身自动对接平台研制

Development of Aircraft Fuselage Automatic Docking Platform

为实现飞机机身对接过程的数字化、自动化和柔性化,研制了分布式机身自动对接平台。阐述了该平台总体构成与设计原理,在详细分析机械系统组成和电气控制系统结构的基础上,完成了平台各系统的集成。利用激光干涉仪器、机身前段样件和机身后段样件对自动对接平台的定位精度、应力控制和自动对接功能进行了测试,测试结果表明:数控定位器定位精度为0.015mm,可满足中机身对接装配精度要求;在调姿过程中前、后段样件的X、Z轴应力较小,不会对机体产生损伤;中机身自动对接平台能够实现中机身前段和后段的调姿、对接及装配完成后对中机身技术指标检测功能。

The overall composition and design principles of the fuselage automatic docking platform are expounded,and the mechanical composition of automatic docking platform and electrical control system architecture are analyzed in detail.The positioning accuracy of the automatic docking platform,stress control and automatic docking function are tested by using a laser interferometric device,the front fuselage sample and the rear fuselage section sample.The test results showed that:The NC locator positioning accuracy is 0.015mm,which may meet the requirements of the fuselage docking assembly precision;During the attitude adjustment,the X,Z-axis stress of the front and rear section samples is less,the body is not damaged;The fuselage automatic docking platform can complete the adjusting posture of the front and rear fuselage and the fuselage technical indicators detection after adjusting posture,docking and assembly.
