Optimal Design On Laser Communication Stabilized Sighting Turntable For Moving Platform

The structure of laser communication stabilized sighting turntable for moving platform on the basis of its principle prototype has been optimized design to improve its performance.This design used the turntable structure of two-dimensional U-O type satisfy the communication technology parameters of the rotary table with the advantage of a simple structure and high precision.First,we have been studied successively statics analysis and dynamic analysis of the turntable which get the stiffness design strength conforms to the technical requirements and the vibration frequency resonance occur not with the outside world.This paper mainly expounds the design of the key structural parts of U-shaped frame and O-shaped frame which plays an important role in the structure of the whole.According to the principle of lightweight design,we got the design optimization by analyzed its key size calculation.Finally,by the pitch axis turntable shaking analyzed,test turntable shafting precision at work,through calculation analysis of measurement results,its shaking error precision within the scope of the license.
