Abstract


In the future "Open space integration" war, air defense is the crucial link to affect the outcome of the war. As an important means of territory and field operation air defense, antiaircraft artillery is an essential part of air defense system. In the past, in the accuracy and damage probability analysis of weapon system, dispersion error of antiaircraft artillery was taken as irrelevant normal distribution error. However, at the situation of current development trends of weapons, small-caliber、high RF antiaircraft artillery has become the development direction, in this case, the correlation of dispersion error of antiaircraft artillery can no longer be ignored.In this dissertation, propose the analysis and test research of dispersion error of a certain type of rapid-fire antiaircraft artillery caused by shooting radial direction impact load. And according to the research, raise a improved method to improve the calculation method of shooting error pattern and shooting efficacy quota of antiaircraft artillery:Firstly, as the most representative link, take first-order inertia link as the filter model, deduce the most simple and practical mathematical model of dispersion error caused by shooting impact load. On this basis, the spatial characteristics and time characteristics of dispersion error caused by shooting impact load are analyzed in theory. Then, based on the working principle and controlling discipline of the direction servo system of a certain type of antiaircraft artillery, construct a dynamic simulation model of the direction servo system on the platform of SIMULINK. On this basis, take the dynamic model of the direction servo system as the filter of shooting impact load, deduce the error of this antiaircraft artillery caused by shooting impact load in theory, and on the platform of SIMULINK, simulate the working performance of the direction servo system as it suffer impact load when shooting, the data from simulation correspond with the conclusion of theoretical analysis. Finally, based on the above research on characteristic of dispersion error of rapid-fire antiaircraft artillery, raise a improved method to improve the traditional calculation method of shooting error pattern and shooting efficacy quota of antiaircraft artillery.This issue is theoretical study of application, the consequent can be used in weapon system of antiaircraft artillery, it can be expected to reduce the cycle and cost of weapons test effectively, this is the development direction of present weapons test.
