Missile's attitude change will be delivered to visual axis through stabilized platform during maneuvering flight  and the missile vibration will be an interference source to visual axis stabilization. In order to solve this problem  the coupling relationship between missile attitude and visual axis is obtained by Coordinate transformation. When the seeker stably tracks a target  the angular velocity of visual axis in inertial space is zero  so the relative angular velocity of roll axis and pitch axis can be derived for servo control. According to Oura dynamics equation  the dynamic models of roll axis and pitch axis were established and kinetic equations of two axises were obtained. The dynamic models can provide theoretical basis to developing research of servo control system and structural optimization design of stabilized platform. Finally  some measures could reduce the dynamic coupling between the framework was given. 2011 IEEE.
