摘要/Abstract

摘要： 针对机翼等大部件装配后姿态调整和精加工等的工艺需求,研制了一种可用于支撑多种机翼的三坐标数控定位器,并对定位器在数字化调姿及精加工平台上的布局和行程进行了分析。将定位器行程解耦成姿态行程和位置行程,建立了适用于多种机翼的定位器行程的目标函数,利用遗传算法获得定位器的布局和最优行程。通过实例对分析方法进行验证,结果表明所提方法是可行的,为大部件调姿中定位器的布局和结构设计提供了依据。

Abstract: Aiming at the process requirement of post alignment and fine finishing after big parts assembly such as wing,a three-dimensional Numerical Control Positioners (NCPs) for supporting various wings was researched,and the layout and stroke of positioner on digital post alignment and fine finishing platform were analyzed.The positioner stroke was decoupled into post and location stroke,and an objective function for positioner strokes of various wings was built.The genetic algorithm was used to find out the optimal layout and stroke of NCP.Through examples,the feasibility of proposed method was verified,which provided evidences for positioners layout and structure design in big part post alignment.

Key words: three-dimensional numerical control positioner, pose alignment, stroke analysis, optimization design
