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 influence of angular displacement and linear displacement caused by vibration of moving carrier on the imaging system is analyzed in detail. Angle displacement is the main factor affecting the imaging quality. The requirements of the imaging base damping system not only to meet the vibration damping efficiency, but also to control the vibration generated during the displacement. A kind of three-dimensional equal stiffness non-angular displacement shock absorber is designed, which not only can meet the requirements of vibration reduction but also control the angular displacement generated during the vibration reduction process, so as to improve the clarity of the moving vehicle imaging system without affecting Boresight pointing accuracy is an ideal shock absorber.
