Research on parametric solid modeling of ammunition rapid design

In order to establish the solid model in ammunition rapid design system, the basic methods of building the ammunition solid model are analyzed. Based on the technology of model decomposition, the basic flow of building the ammunition solid model is expounded, and the solid model of the ammunition parts is established by using the parameterization method. The ammunition graphics library is build up based on the temporary model library, sharing model library and digital template library. The research of ammunition parametric solid modeling lays the foundation for the establishment of ammunition rapid design system.
