| As an important weapon equipment of the modern army,under the background of greatly improving the performance of tank weapons,tanks need to give full play to their own mobile advantages in the battlefield,improve the operational efficiency of weapons,and ensure their own survival probability.Therefore,the implementation of moving shooting is the task that must be completed in the future tank operations.In order to study the problem of hit error in moving firing,this dissertation analyzes and summarizes the assumption and estimation of motion law in tank moving to moving firing,and analyzes the causes of error in firing process.In view of the influence of the carrier on the additional velocity of the projectile,the exterior ballistic model of the tank moving shooting is made.The superposition of the velocity of the vehicle on the projectile is analyzed,and the error result is simulated.Then,the influence of barrel on projectile’s implicated velocity caused by turret rotation is analyzed,and its influence on external trajectory is simulated and analyzed.This part of the error is corrected by the new trajectory equation.Aiming at the influence of barrel random vibration on moving shooting,the force of tank system is analyzed,and the dynamic model of tank system is obtained by decomposing and modeling the body gun system.The statistical characteristics of barrel random vibration are obtained by using the hierarchical modeling of different grades of road roughness as the input of tank dynamic model.Through the trajectory model of the moving shooting,the impact point dispersion of the projectile is obtained,the error is analyzed,and the control strategy of the shooting door is modified,and the simulation is made and analyzed. |
