摘　　要：详细分析了由动载体振动引起的角位移和线位移对成像系统的影响。角位移是影响成像质量的主要因素。对成像底座减振系统的要求既要满足减振效率,又要控制减振过程中产生的角位移。设计了一种三向等刚度无角位移减震器,它既能满足减振要求,又能控制减振过程中产生的角位移,从而提高了动载体摄像系统的清晰度,同时又不影响视轴的指向精度,是一种比较理想的减振器。The effect of vehicle vibration, including angle displacement and linear displacement on the imaging quality of the imaging system is analyzed. To conclusion that effect of angle displacement is the major element is given. To mount isolators of image systems should satisfy the vibration efficiency of the reduction vibration and control angle displacement in the process of reduction vibration. 3Dimension, equal stiffness, irrotational displacement isolator not only can satisfy the reduction vibration efficiency, but also control angle displacement is designed. It can improve the definition of image system on moving vehicles, and can not damage the directional precision of visual axis.
