摘　　要：针对传统机翼壁板自动钻铆误差大、效率低的问题,结合有限元法和解析法提出了一种可以适应不同托板组合方式下托架变形求解的算法。借助有限元分析数据,运用三次样条插值、拟合变形包络曲面等方法构造了托架变形计算式,并提出了相应变形补偿算法。A new algorithm is presented for the deformation calculation of bracket. The algorithm is formed by combining the finite element method with the analytic method. The formula of deformation and compensation algorithm are constructed by using cubic spline interpolation, envelope surface fitting according to the result data of finite element analysis. Practical results show that the accuracy and efficiency are improved by using our algorithm.
