Abstract

The pointing angle of two-frame coordinator driving by separated rear frame is comprehensively considered. The geometrical model of two-frame coordinator driving by separated rear frame is built, The calculation method of the yaw and pitch angles of the front frame of the coordinator is given based on the coordinate transformation and the spatial geometry relation between the front and rear frame, together with the features of the coordinator’s drive system, and the functional relations between the front frame pointing angles and the rear frame driving angles, the length of the inner frame linkage and the length of the back inner ring rocker arm are obtained. By solving the function equation numerically, the change trend of the front frame pointing angles followed by the rear frame driving angles is analyzed. The result shows that the pointing angles of this two-frame coordinator cannot be simply replaced by the rear frame driving angles, and the influence of the type of frame transmission on its pointing cannot be ignored.

Key words： two-frame coordinator; driving by separated rear frame; the front frame pointing angles; the rear frame driving angles
