Abstract: The current invention is associated with Physics-Based Gun Barrel Wear Monitoring and Life Prediction System that aims to assess structural damage of gun barrels used in high-pressure firing which is a cyclic exercise of medium caliber guns. Gun barrels undergo severe thermo-mechanical loads such as high internal pressure, elevated temperature increase, and shock loading during firing operation. These circumstances eventually cause material fatigue, thermal stress build-up, micro-crack development and bore surface erosion that can decrease the structural integrity and working life of the barrel unless properly monitored. The proposed system offers real time monitoring and predictive maintenance system by incorporating temperature sensors, strain gauges and vibration sensors in order to measure operational parameters of the gun barrel during the firing cycles. The sensor data received is interpreted in an embedded processing unit which makes signal conditioning and analytical computation processes relying on well-known rules of mechanical engineering. This system uses the equations of thick-cylinder stress, and the stresses generated by internal firing pressure are the radial, hoop, longitudinal stresses. The thermal stress due to quick change in temperature is measured based on thermal expansion relations and cumulative fatigue damage is measured based on fatigue life analysis models. Referring to these calculations, the system defines the wear state of the barrel and foretells the rest of the safe firing cycles. A Health Index (HI) is made to indicate the structural status of the gun barrel and the system categorizes operational state either as safe, warning or critical. The findings are presented in a format of an operator monitoring interface where the maintenance staff can monitor wear trends and carry out preventive maintenance on time.
