Precision Analysis and Layout Rules of Surveying Control Network for Aircraft Assembly
摘要
Abstract
High precision surveying control network was presented for meeting the large space , high precision and dispersed point’s requirements of an aircraft assembly .A surveying control net-work was constructed with the public points which were long term laid out on the ground of the as-sembly plant by tracker laser .Using the public points ,the global coordinate system of the aircraft as-semble was built .Combining the approximate coordinate transformation and least square principle , the formula of surveying control network errors was derived .Combining the 2-norm method and ine-quality transform ,the relationship between the public point errors and surveying control network was studied and the transfer coefficients of point errors were concluded .Using the normal equation and positive matrix ,the relationship between the point number and the surveying control network preci-sion was determined .Finally ,layout rules of the surveying control network were proposed .关键词
