Method of Gun Barrel Life Prediction Based on BP Network

Aimed at the problem in the gun barrel life prediction, a method of gun barrel life prediction based on record of firing was pointed out. On the basis of internal trajectory resolving, the equivalent life transform coefficient for gun barrel based on the overall heat in origin of rifling and the overall gun pressure was computed. And by assuming we wore gun barrel life in canonical record of firing, a conversion model between the equivalent life transform coefficient for gun barrel and variety of record of firing which could be used to realize the gun barrel life prediction was built by using BP network.
