Remote Control Weapon System(RCWS) is the advanced defense systems to fire the long-distance target with the maximum security to the operator who is located in remote and safe place. It is able to search, chase and even shoot the target automatically. Like other weapon systems, the shooting accuracy is one of the most important performance indexes. While multiple shooting involves extremely fast and complex momentum transfer, it is a very challenging engineering problem to attain the extreme accurate shooting. In this paper, shooting simulation model for RCWS is developed to replace live fire in South Korea and to optimize the dynamic performance of the entire system. The entire system is composed of the gun, the mount and the flexible body. The internal movement of the gun during shooting is modeled with the multi-body dynamic model and correlated with the actual response. Equivalent stiffness technique is adapted to reduce the degree of freedom in flexible body and the computation time drastically. The simulation model shows a practically good agreement with the actual shooting experiment, which opens wide possibility to replace the actual shooting experiment in the development phase.
