Real-time Simulation Based on Multi-body Dynamics in Virtual Reality of Gun

The research is focused on virtual reality(VR) technology with its application to virtual prototyping of gun systems.Based on software platform,MultiGen Creator and Vega,the virtual reality system of gun was developed.The software and hardware requirements of the system were demonstrated.The solution was presented,such as the modeling method based on MultiGen Creator and the implement of the whole system.A dynamic simulator for self-propelled gun was set up.The simulation results show that this virtual system can demonstrate the simulation process of gun launch realistically,and it satisfies the real time requirement of system simulation,which can be used for designing and optimizng the gun system.
