大型客机机身对接技术研究

Research on Docking Technology of Large Aircraft Fuselage

为解决当前国内大型客机机身对接准确度较低的问题,对某大型客机机身的对接方法进行了研究。首先,对机身的对接基准和机身对接工装进行了选择和设计。在机身对接过程中,先使用激光准直仪,通过人工调整使激光准直仪光线聚合,直到数显表上显示需要的数据为止,从而对机身位置进行调整。再应用激光跟踪仪对机身装配基准点的实际坐标值进行测量,在线测量控制系统根据测量的实际坐标值数据对中前机身进行微调以满足机身对接的位置要求。最后,根据机身微调后测量出的基准点的实际坐标值与理论坐标值的距离平方和的根来判断机身对接是否达到标准。该机身对接的方法可以合理地将机身对接的偏差控制在容差范围内。通过对大型客机机身对接技术的研究,得出以激光跟踪仪、激光准直仪、在线测量软件和伺服传动装置为主要机构的在线测量控制系统,可以大幅度提高大型客机机身对接的准确度。

In order to solve the problem of low accuracy of the fuselage of large aircraft in China,this paper studies the docking method on the fuselage of a large aircraft.First of all,this paper selects and designs the docking datum of the fuselage and the docking station of the fuselage.Later,in the process of the fuselage docking,using a laser collimator,make the laser collimator light polymerization through artificial adjustment,and the desired data displayed on the digital display table,so as to adjust the body of the aeroplane.Again measuring actual coordinates of fuselage assembly datum using laser tracker,online measurement control system trims fuselage according to the actual coordinates measurement data to meet the requirements of the position of the fuselage and docking.Finally,according to the fine-tuning of the fuselage,the actual sitting value of the measured reference point and the square root of the sum of distance squares of the theoretical coordinates are used to determine whether the fuselage butt meets the standard.The method of fuselage docking in this paper can reasonably control the deviation at the tolerance range.Through the study of large aircraft fuselage docking technology,laser tracker,laser collimator,online measurement software and servo drive device as the main body of online measurement control system,can greatly improve the accuracy of large aircraft fuselage docking.
