Impact Response Analysis of Radome Based on DDAM Method
Considering a certain type of radome,the impact response of the radome was analyzed by using the finite element analysis software ANSYS and dynamic design analysis method(DDAM).The stress and displacement response of the radome structure under the longitudinal,transverse and vertical impact responses were investigated.The results show that the radome achieves the largest displacement and stress response under the vertical impact load.Its maximum Mises stress is 42.1 MPa,which is less than the material strength.Its maximum displacement is 40.356 mm,which meets the structural stiffness requirements.Therefore,the radome is safe and reliable under the impact load and satisfies the normal working requirements.
