Dynamics Simulation Of The Gun System Based On Virtual Prototyping Technology

Based on the virtual prototyping technology, and commercial software platforms, the dynamic behaviors of a gun system have been systematically simulated and studied.Firstly, the worldwide research activities of the gun system are reviewed, and the fundamental principle and cooperating process of the system are introduced. Then, the gun system is simplified both as a rigid body system and as a rigid-flexible system.Secondly, a 3-dimensional digital model is established by the CAD software, Solidworks. The best file transfer protocol between Solidworks and ADAMS is found, and the model of the gun system is successfully imported to ADAMS software.Thirdly, at the platform of ADAMS, the virtual prototype of the model is founded, by using the toolbox of ADAMS and Fortran language to apply constrains and forces to the parts of the model. Using the virtual prototype, dynamic simulations of the multi-rigid-body gun system are carried out under the conditions of single, repeating and planar revolving shoots. The preload of the special spring, which is an important parameter affecting the dynamic behaviors of the gun system, is optimized for the single and repeating shoots.Finally, a rigid-flexible coupled virtual prototype of the gun system is established when the material properties of the fixing ring is taken into account, and the dynamic behaviors of the rigid-flexible gun system are initially analyzed.The research in this paper provides some valuable conclusions and simulation approach for the design and experiment of the gun system, which can effectively reduce the manufacturing periods and cost of the system.
