Finite Element Modelling and Simulation of Gun Dynamics Using "ANSYS"

The dynamic response of the gun during the firing cycle and the relative motion of the projectile with respect to the barrel has a significant effect on the accuracy and consistency of the gun as well as the shot launch conditions. Computer modelling techniques can be used to simulate motion of the gun during the firing cycle. A three dimensional finite element model of a large calibre gun was developed using ANSYS commercial software and its motion during the firing cycle was simulated to study and predict the effects of various design factors on the dynamic response of the gun. Physical contact conditions of the gun system components have been modelled using contact technology in ANSYS. Results are compared with general responses of the gun system obtained through available docummented sources. Effectiveness of the software for accurate modelling of gun dynamics is discussed.
