回转体类零件四自由度姿态调整解耦问题的研究

Study of decoupling problem of four freedom attitude adjustment for gyrorotor specimen

为减小测量误差，对高准确度回转体类零件的形位误差测量必须进行姿态调整，即四自由度α－β（倾角）、ｘ－ｙ（偏心）调整，当各调整功能之间存在“耦合”影响时，使得调整费时甚至调不出预定的定位准确度。为此，提出解决调整功能之间耦合问题的方法和模型，较系统地解决了这一问题。

In order to reduce measurement error, the attitude of the gyrorotor specimen must be adjusted while its form position error is measured. It will need four freedom: α β(inclination)and x y(offset) adjustment. When “coupling” effect is existed in every freedom adjustment, which will lead to that the total adjustment need long time and even can not reach the designate accuracy. For this reason, the method and model to solve the decoupling problem are put forward, so that decoupling problem is solved systematically and satisfactorily.
