| Abstract |
The strong engraving and large deformation processes of multi-layer metallic materials with an initial impact are studied in this work based on a new propulsion pattern under a new two-stage combustion technology from two types of propellants that can improve the launch stability and safety
of the vehicle composed of multi-layer metallic materials. The research focuses on analyzing the stress-strain characteristics, which involve complex interactions between multi-layer materials and the
steel launcher. This is achieved through the development of a comprehensive dynamical model in conjunction with two-stage ignition combustion ballistic equations. Simulation results are meticulously
compared with experimental data to validate the accuracy of this intricate coupled model. Further, the
influences of the launcher structure on the deformation and engraving characteristics of the vehicle
are also investigated, demonstrating that the launcher structure can obviously affect the stress-strain
distribution and the groove patterns with obvious variations of engraving resistance generated in the deformation motion process of the vehicle. Based on this, this work also obtains the impact engraving
resistance equations under different conditions. By integrating theoretical modeling with experimental
verification, the study provides valuable reference into optimizing the design and operation of vehicles composed of multi-layer metallic materials, thus contributing to advancements in launch stability and safety technology. |
