Gun Charge Recognizing Simulation Based on Maximal Recoil Acceleration
To recognize gun charge using the maximal recoil acceleration,the recoil acceleration calculation model was built up based on the interior ballistic trajectory model and the recoil system model.Through simulation,the effect on the maximal recoil acceleration of the gun structural parameters and firing parameters which change in the actual operation condition was analyzed and the fact was found that the gun charge can not be effectively recognized only using the maximal recoil acceleration for the chamber enlargement and the powder temperature have remarkable effect on the acceleration.So the plan using the maximal recoil acceleration and the powder temperature to recognize gun charge was adopted which considering the four phases of the chamber enlargement at the same time.The recognizing model was set up using the artificial neural network and the simulation test indicates that the recognizing model has 100%correct recognizing rate to the gun charges.
