This paper presents a new type of flexible structure of the gimbal device, the device is composed of multiple flexible supporting structure and cross butterfly voice coil motor, which can realize multi degree of freedom movement, compared with the traditional two-axis four-frame structure, has the advantage of high precision, no friction and compact bodies, and can improve the whole stability of stabilization system precision. The modal simulation of the whole flexible support gimbal is carried out by using ANSYS software, and the results show that the gimbal meets the performance requirements of the stabilized aiming system and can realize multi-degree-of-freedom movement. Finally, through the simulation comparison between the FSM structure and the stabilized aiming system of the universal frame device, the result show that the stability accuracy of the system after FSM compensation is 10urad, while the accuracy error of the flexible structure gimbal is not greater than 5urad, that is, the stability accuracy of the device can be improved.
