Dynamic Finite-Element Simulation on The Phased Array Radar Antenna Multiplex Damage By Fragment and Shock Wave

摘要：

　　Based on the nonlinear dynamic explicit finite element software LS-DYNA 3D,the parameters of detonator and Constitutive models of air,fragment and the Phased Array Radar Antenna Equivalent panel were ascertained,Numerical Simulation of target multiplex damage of fragment and shock wave was processed.The simulation results of shock wave overpressure,the board plastic deformation and the camber of the board unit near the perforation are consistent with theoretical analysis and experiments,the simulation method and parameters are proved to be reliable and helpful for researching the equipment structural impact multiplex damage caused by fragment and blast.and the paper puts ting forward to a reasonable and convenient method which could analyze the weapon equipment structural impact multiplex damage mechanism caused by fragment and wave.
