To improve the accuracy of an altitude axis precision model,the centerpart,a main part effeting altitude axis precision is analyzed by the Finite Element Method(FEM),and then the curve of altitude axis max deformation versus pitch angle is obtained.
通过对影响1 m望远镜俯仰轴系精度的主要因素—中间体(四通)的有限元分析和运算,得出了四通在不同俯仰角度的变形曲线,并与实际检测结果进行对比,找出两者的相同特征并进行了补偿。
