An in-situ artillery calibration system for armored vehicles based on photoelectric self-collimation method
In order to solve the current problems of restricted time and space,low accuracy,complicated process and inability to proofread artillery in situ for armored vehicles,an in-situ artillery calibration system for armored vehicles based on photoelectric self-collimation method was proposed.Based on the principle of mirror gun consistency,the mechanical structure of the artillery calibration device was designed;The parallel light tube and its internal optical structure were constructed to simulate the virtual target at infinity by using the principle of optical self-collimation;The error model of the artillery calibration device was established,the accuracy of the parameters of the artillery calibration device was evaluated by the analysis and synthesis of the error model,and the maximum error value allowed by the device was determined;The performance of the system was tested and verified through the experiments.The results show that with the error model designed,the calibration error is no more than 60%of the traditional proofread artillery,and the time is shortened by more than half,which meets the design requirements and has strong stability.The in-situ artillery calibration system can be applied to the artillery calibration of armored vehicles to improve the efficiency and accuracy of the artillery calibration and to achieve the in-situ calibration on the spot,which provides a new method and a new way of thinking for the artillery calibration of armored vehicles.
