【 摘 要 】
In this paper, firstly, based on the basic control equations of fluid mechanics, the effects of the fluid on force and vortex induced vibration around underwater submarine model are studied and discussed, employing the finite volume method by hierarchy grids. Secondly, the structural characteristics, transfer functions and control strategies of Steering Mirror Fast (FSM) are analyzed and obtained. The disturbance of moment also has been resolved to optical axis coordinate system. Finally, take the optical model of submarine as the research background, the effects of the FSM on the stability improvement of photoelectric tracking system are discussed. The results show that the disturbance of submarine moments mainly origin from the vortex induced vibration. The dynamic target tracking error could be suppressed. This research explores vortex induced vibration control in optical filter. Therefore, it holds certain scientific significance and practical value.
