The Optical-Mechanical Structure Design Of Stable Precision Measuring Device Of Cannon

Dynamic feature of Weapon equipments is one of important performance indexes for evaluating the performance of the whole weapon system. The construction of target range in our country in fire control dynamic testing is relatively backward; therefore, it has greatly influenced the evaluation on the fire control system. In order to solve this problem, it’s urgent to develop a new testing instrument so as to adjust to the armament research process and promote weapon system working more efficiently and thereby meeting the needs of modernization in national defense.In this paper, the design of real time tracking and measuring device of the cannons is to meet the needs of the demand. The measuring device adopts the two methods—visual optical system and CCD sending-receiving system, for tracking image: it also adopts digital image-forming and image processing technique for real-time measurement and storing of the target information; it simultaneously adopts the method adjusting the platform and the corresponding fixture mounted on a sample to measure the stable precision and the precision of corner of stabilizator. The precision of measurement can amount to0.1mil.
