摘　　要：针对传递对准过程中存在的动态挠曲变形的问题,本文提出了一种"量测失准角+速度"匹配的快速传递对准方法。通过将动态挠曲变形模型的相关变量引入到传递对准状态方程中,从而降低动态挠曲变形对传递对准精度的影响。仿真结果表明,该方法有效降低了动态挠曲变形对传递对准精度的影响,满足传递对准的高精度和快速性要求。In view of the problem that dynamic flexure deformation exists in the process of transfer alignment,a new ＂measurement misalignment angle ＋ velocity＂matching method is proposed in this paper. By adding the related variables of dynamic flexure deformation model to the transfer alignment equation of state,the influence of dynamic flexure deformation on the transfer alignment accuracy can be reduced. The simulation results show that the proposed method effectively reduces the influence of dynamic flexure deformation on the transfer alignment accuracy,and can meet the requirements of accuracy and fastness on the transfer alignment.
