飞机壁板装配偏差传递与演变及其优化方法OA
Transfer and Evolution of Aircraft Fuselage Panel Assembly Deviation and Optimization Methods
壁板的装配准确度直接影响飞机的气动力特性,在装配过程中受到夹紧力、铆接力、回弹力、装配顺序等影响,壁板将发生不同程度的变形,装配变形与零件偏差、夹具偏差等相互耦合,导致壁板最终的装配准确度难以预测和控制.针对以上问题,本文对壁板装配过程中偏差的传递与演变规律进行研究,构建了壁板装配偏差传递与演变的刚柔混合模型与壁板装配准确度的评价准则;采用确定性分析法计算壁板的刚性定位偏差,并通过建立多步夹紧和不同长桁装配顺序下的偏差状态空间模型,揭示了壁板装配过程中偏差的演变规律,实现了壁板装配偏差的准确预测;提出了基于代理模型和智能优化算法的长桁装配顺序稳健优化设计方法,通过装配顺序优化使壁板的装配质量得到了整体提升.
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.
