Assembly-Ariented Optimization Design of Positioning Quality for Aircraft Integral Strengthening Frame
In order to reduce the influence of manufacturing differences on the assembly positioning quality of aviation integral re-inforcing frame and solve the problems of poor control of positioning process and low repeatability of positioning results caused by forced positioning,an adaptive positioning method of aviation integral reinforcing frame is proposed based on force control tech-nology.First,after the assembly positioning is completed according to the traditional forced method,the position of several coor-dinate positioning holes is adjusted within the allowable range of design,and the force load value at the hole position meets the adaptive positioning requirements.Second,aiming at the requirements of shape and position accuracy and assembly stress level in the assembly positioning process of aviation integral reinforcing frame,the evaluation standard of assembly positioning quality is quantified.Then,based on the orthogonal test,the variation law of the absolute average value of force load at the positioning hole and the absolute average value of stress at the positioning detection point is analyzed,and the feasibility study of replacing the stress value with the force load value easily obtained at the assembly site is carried out.Finally,the force load adjustment tar-get at the coordinate positioning hole is obtained by modifying the quantitative formula of the assembly positioning quality evalu-ation standard to guide the assembly positioning of aviation integral reinforcing frame.
