Research on dynamic response test and numerical simulation of the torpedo impacting the target

LI Jing-xiao;CHEN Yan-yong;ZHANG Tao;XU Da;The 705 Research Institute of CSIC;  
The target typical structure damage deformation and dynamic response during the process of torpedo impacting was studied experimentally, firstly, the two impacting condition was predicted by FEM numerical simulation, then, the effects of impact parameters on results was studied experimentally. The result show that the faster of the striker, the target deformation is more obvious, and acceleration response is more rapid. The thicker of target thickness, the target deformation is weakened, and acceleration response is also more rapid. And the results of two methods were compared, the result show that the result based on test and numerical simulation are well matched, the numerical simulation method in the paper can predict the dynamic response during the torpedo impacting the target.
