Aiming at the problem that large elastic deformation of Gatling gun tripod during the shooting process is an important factor affecting the firing accuracy, mesh morphing and approximate model technique are comprehensively applied to the multi-objective optimization of gun tripod for improving its rigidity. Rigid-flexible coupling virtual prototype model of Gatling gun is built and the shooting process of the gun is dynamically simulated. The feasible of the model is verified through the comparison between the simulation data and the test data. Virtual prototype model with optimized gun tripod using mesh morphing technique is established, and the shooting dynamic characteristics of the optimized model and the original model are compared. The vibrant angular displacement and speed of muzzle in perpendicular direction are significantly reduced, and a 12.16% quantity of the radius of 70% dispersion circle is achieved. The results indicate that the optimized tripod can effectively suppress the vibration of gun system in the perpendicular direction, and improve the density of dispersion.
