The Virtual Test of Impact Damage on Weapon System Based on SPH Numerical Simulation Method
The problem of impact damage widely exists in various types of weapons and equipment,and seriously affects their use and lifespan.Currently,there is no universally applicable basic model for virtual experimental research on impact damage.This article focuses on the construction of basic model for impact damage virtual testing,and discusses the basic principles of smooth fluid dynamics and the application of its numerical simulation method in impact damage virtual testing.An improved smoothed particle hydrodynamics(SPH)numerical calculation model is constructed,and the particle processing and material boundary treatment of physical models are discussed in detail.Simulation calculations are conducted on the impact of typical rigid particles on the impact copper target plates,verifying the reliability and accuracy of the simulation.The damage situations of target plates impacted by the rigid particles with different edges and angles are compared and analyzed,fully demonstrating the applicability of the SPH method in virtual impact damage testing.
