Layered Mapping Method of Local Displacement Field for Panel Deformation Prediction

Abstract

Abstract: Aiming at the problems of long calculation period of panel riveting deformation prediction simulation in aircraft assembly processes, according to the idea of local-global mapping method, a layered mapping method was proposed based on local displacement field，and a mapping model was established. And the finte element analysis results of proposed model and 3D dynamic model were compared. The research results show that the proposed method may effectively reduce the simulation time, and increase the reliability of the actual drilling riveting processes. The relatively errors of axial displacement are as 2.2% by using the proposed method. The calculation time of a single rivet is decreased from 45.56 min to 3.33 min, when the mapping area is in the range of 2.5R(R is the radius of the rivet hole). Besides the effectiveness of the proposed method was verified by three rivets model.

摘要： 针对飞机装配过程中壁板铆接变形预测仿真计算周期长的问题，依据局部-整体映射的思想，提出了基于局部位移场的分层映射方法，建立了映射模型，并将所提模型与三维动态模型的有限元分析结果进行了对比。研究结果表明：所提方法可有效地缩短仿真计算时间及提高模拟实际钻铆过程的可靠性；采用所提方法时的轴向位移相对误差为2.2%；当映射区域为2.5R(R为钉孔半径)时，单钉铆接的计算时间由45.56 min缩短至3.33 min。通过三钉模型验证了所提方法的有效性。
