Study on Finite Element Model Construction of Non-lethal Kinetic Energy Projectile SIR-X
摘要
Abstract
In order to solve the problem that conventional experiments are difficult to characterize the motion attitude and deformation characteristics of NATO standardized non-lethal kinetic energy projectile SIR-X,and the type is single and expensive,finite element method is used to give the linear elastic material model(* MAT_ELASTIC)of the projectile body and the visco-hyperelastic material model(*MAT_SIMPLIFIED_RUBBER/FOAM)of the projectile nose,and the finite element models SA and SB are constructed by combining A and B material cards to simulate the blunt impact experiment of the rigid wall.The comparison of the finite element model SA2 and SB2 is constructed by optimizing the mesh division.The results show that the finite element models constructed by the two materials cards meet the validation corridor defined by AEP-99,material A is suitable to determine the safety upper limit of injury of SIR-X,material B is suitable to determine the valid bottom limit of injury.关键词
