飞机壁板装配偏差传递与演变及其优化方法
Transfer and Evolution of Aircraft Fuselage Panel Assembly Deviation and Optimization Methods
摘要
Abstract
Due to the influence on clamping force,riveting force,resilience force,assembly sequence and other parameters in the assembly process of skin and stringer of aircraft wing panel,different degrees of deformation will occur.Assembly deformation is coupled with part deviation and fixture deviation,which makes the final assembly accuracy of the panel difficult to predict and control.In view of the above problems,this paper studies the transfer and evolution of deviation in the process of panel assembly,and constructs the rigid-flexible hybrid model of the transfer and evolution of panel assembly deviation and the evaluation criterion of panel assembly accuracy.The rigid positioning deviation of the panel is calculated by the deterministic analysis method.By establishing the deviation state space model under multi-step clamping and different stringer assembly sequences,the evolution law of the deviation in the panel assembly process is revealed,and the accurate prediction of the panel assembly deviation is realized.A robust optimization design method of stringer assembly sequence based on surrogate model and intelligent optimization algorithm is proposed.The assembly quality of panel is improved by assembly sequence optimization.关键词
