At present the installation of aeroengine overall unit to the aircraft body is mostly realized by manual work
with man-powered vehicle. To solve its defects of poor efficiency, high labor intensity, easy scratch of aeroengine and so
on, a kind of precise numerical-controlled (NC) installation method has been studied. An aeroengine NC installation vehicle
based on visual monitoring was developed. And the freedom of the multi-axis attitude adjusting platform in the vehicle was
analyzed. Experimental researches have been accomplished for the installation of aeroengine. Experimental results showed
that the method and the equipment for aeroengine NC installation had the superiority of convenient operation and high
visual degree. The efficiency of the installation for aeroengine was increased by more than one time with the location precision
being limited in 0.2mm and the attitude precision being limited in 20' . Meanwhile, the scratch between the aeroengine
edge and the engine cabin is avoided in the installation process.

ZHANG Qiuyue, AN Luling
DOI: 10.16080/j.issn1671-833x.2017.11.040
Virtual reality (VR) and Augmentation reality (AR) have been applied to aircraft assembly with the development
of computer technology. A full three-dimensional virtual environment can be built with the use of AR. Virtual
information can be superimposed on the reality environment with the use of AR. Mixed reality (MR) which combines the
advantages of both, allows more realistic human-computer interactions, and provides more focused and comprehensive
assembly information while the modeling work can be greatly reduced. MR-based virtual assembly system can manage a
great amount of information and data centrally, which means lead time and the waste of resources will be greatly reduced.
The channels and scope of access to information can be expended, the important assembly information can be augmented,
the requirement of workers’ visual space ability can be reduced when applying the mixed environment to complete the assembly.
Based on the above, the virtual assembly system can help to reduce the assembly error, shorten the assembly time,
and improve assembly efficiency and assembly quality.

To solve the high-cost of frequent maintenance of public reference points which are widely used to build
global coordinate system in the digital aircraft level adjustment recently, a novel level adjustment method for aircraft without
public reference points was proposed. The mathematical model of horizontal coordinate system without public reference
points is established, and the horizontal coordinate system is built with the moveable dual-axis inclinometer of high precision
and the mounting base of inclinometer. Based on the horizontal coordinate system, the horizontal posture of aircraft
is calculated, and numerical control positioners are driven to move coordinately to achieve aircraft level adjustment. Then
the test system for the level adjustment of aircraft is developed. Besides that, an application experiment on a certain type
aircraft has been conducted in the assembly plant, which demonstrates that the level adjustment precision of test system is
better than 0.4 mm, and the horizontal coordinate system can provide an accurate adjustment datum for the whole adjustment
process. The method can complete the level adjustment process ideally, and also improve the efficiency and precision
of measurement and adjustment.

foam reinforcement at the same condition. Vibrational acceleration time-domain signals in the milling process were analyzed
and compared as well as machined surface quality and part deflection. And the signals in frequency domain obtained
by Fast Fourier Transform (FFT) with MATLAB software were also analyzed and compared. Finally, the experiment results
show that polyurethane foam reinforcement can significantly improve cutting stability, obtain better surface quality and reduce
part deformation.

99 Machining Deformation Error Compensation Method of Aluminium Alloy Thin-walled Parts Based on the Ruled Surface Reconstruction
DOI: 10.16080/j.issn1671-833x.2017.11.099
Due to the low-rigidity of the thin-walled parts, it was difficult to guarantee the quality of NC finish machining
by conventional single geometric programming. According to the multi-step iterative compensation method, the
tool path optimization algorithm based on cutting deflection error compensation was proposed by reconstructing compensatory
surfaces of ruled surface to correct the original tool paths. Finally, the cutting experiment was carried out based on the
algorithm. The result shows that the method of the machining deformation error compensation is correct and reliable.
