Flack Spread Impact Load Moving System Errors Weak Correlation Analysis And Simulation

Anti-aircraft guns as an important means of territory and field of air defense, is an important part in the future space integration war. In the traditional analysis of anti-aircraft gun, anti-aircraft gun spread error is being unrelated normal participate in shooting effectiveness analysis of weapon system. However, in the current development situation, anti-aircraft gun of high frequency has become the mainstream of anti-aircraft gun weapon system, so the anti-aircraft gun spreading error’s weak correlation has the meaning of practical considerations.In this paper, the anti-aircraft gun servo system’s weak correlation properties of spreading error caused by impact load are analyzed in theory and a simulation test was carried out: first of all, in a certain type of anti-aircraft gun, based on the working principle of the anti-aircraft gun position servo system and control law, build the dynamic simulation model of the position servo system. On this basis, improve the dynamic model of the position servo system to make it into a first-order model. Secondly, the type of anti-aircraft gun servo system’s weak correlation characteristics of dispersion error under the impact load is derived and analyzed theoretically, and it is concluded that for the second order model exist an optimal firing interval rate of fire of anti-aircraft gun which can guarantee the rate of fire and make the spread of error correlation coefficient is small. Research on the improved servo system obtained the quantitative relationship between the dispersion error’s multi-step correlation coefficient and the parameters of anti-aircraft gun servo system. On the SIMULINK platform the anti-aircraft gun position servo system is simulated and the simulation data is consistent with theoretical analysis of the conclusion. Finally, introduce the weak correlation of the anti-aircraft gun scattered error to the traditional anti-aircraft gun shooting error model and the kill probability.This topic is the application of basic theory research, the mathematical model is typical representative and the results for similar artillery systems have lateral extension. Expect it can offer theoretical reference for the design of anti-aircraft gun weapon system, shorten weapons test cycle and reduce test cost.
