A new principle and device for large aircraft components gaining accurate support by ball joint

Abstract:How to obtain an accurate support for large components by ball joint is a key process in aircraft digital assembly. A novel principle and device is developed to solve the problem. Firstly, the working principle of the device is introduced. When three or four displacement sensors installed in the localizer are touched by the ball-head, the spatial relation is calculated between the large aircraft components ball-head and the localizers ball-socket. The localizer is driven to achieve a new position by compensation. Relatively, a support revising algorithm is proposed. The localizers ball-socket approaches the ball-head based on the displacement sensors. According to the points selected from its spherical surface, the coordinates of ball-head spherical center are computed by geometry. Finally, as a typical application, the device is used to conduct a test-fuselages ball-head into a localizers ball-socket. Positional deviations of the spherical centers between the ball-head and the ball-socket in the x, y, and z directions are all controlled within ±0.05 mm under various working conditions. The results of the experiments show that the device has the characteristics of high precision, excellent stability, strong operability, and great potential to be applied widely in the modern aircraft industry. 作者: Author: Bao-gui QIU  Jun-xia JIANG  Ying-lin KE 作者单位: The State Key Laboratory of Fluid Power Transmission and Control, Zhejiang University, Hangzhou 310027, China 期 刊: 浙江大学学报(英文版)(A辑:应用物理和工程)   ISTICEISCI Journal: JOURNAL OF ZHEJIANG UNIVERSITY SCIENCE A 年,卷(期): 2011, 12(5) 分类号: V26 Keywords: Aircraft digital assembly    Large aircraft component    Accurate support    Ball joint    Displacement sensor    Three coordinate numerical control localizer    机标分类号: O61 V27 机标关键词: aircraft components    typical application    working principle    spatial relation    high precision    results    points    modern    center    three    novel    based    four    new    key 基金项目: the National Natural Science Foundation of China,the Natural Science Foundation of Zhejiang Province,theFundamental Research Funds for the Central Universities of China
