发明名称 INERTIAL SYSTEM OF STABILISATION OF IMAGE OF OPTICAL DEVICES
摘要 FIELD: instrument making.SUBSTANCE: inertial system of stabilisation of an image of optical devices comprises an inertial platform installed on the device body with the capability of rotation relative to the axis, a spring that connects the movable platform with the body, a damper of vibrations on the basis of vortex currents, a damper compensator, comprising a sensor of angular speed, installed on the device body and connected to the input of the amplifier of the signal of the angular speed sensor, a moment drive of a movable platform connected with the output of the amplifier of the signal of the angular speed sensor and creating the moment of forces applied to the movable platform, proportionate in amplitude to the angular speed of the device body, but directed oppositely. The damper compensator is installed so that its coefficient of effectiveness µ correlates with the coefficient of efficiency of the damper ? as 0.1??µ??. The moment drive of the movable platform is a solenoid with a coil installed on the body and a core of a solenoid installed on the movable platform.EFFECT: increased coefficient of damping of body oscillations with simultaneous suppression of movable platform swinging at resonant frequency.3 cl, 4 dwg
