机翼数控定位器布局及行程优化

针对机翼部件装配后姿态调整和精加工的需求,研制了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及其在平台内投影的行程进行了分析;根据定位器行程在平台上的投影为长方形的特点,建立了数控定位器行程的优化函数,利用遗传算法计算出定位器的最优布局和行程范围;最后,通过实例对分析方法进行验证.结果表明:所提出的方法是可行的,为机翼柔性支撑中定位器的布局和结构设计提供了依据.

Layout and Stroke Optimization of Numerical Control Localizer for Triangle Wings

To meet the need of posture alignment and fine finishing of wings after assembly,a threedimensional numerical control localizer for various wings flexible supporting was developed. The layout and projection stroke on the platform of the numerical control localizer were analyzed. Optimization functions of numerical control localizer stroke were established based on the rectangle characteristics of localizer projection on the platform. The genetic algorithm was used to find out the optimal layout and stroke of localizers. Finally,an example of the algorithm was verified. Results show that the proposed method is feasible,and provide a basis for wing flexible supporting layout and three-dimensional numerical control localizer structure design.
