Algorithm research on vertical penetration depth calculation

In this paper,the principle of algorithm for ANSYS/LS-DYNA software simulation is introduced,through the establishment of a model of missile vertical penetration steel-target for explicit dynamic analysis.By MATLAB,a method of computing penetration depth based on acceleration is presented,which meets the standards of penetration depth algorithm.Using this method to take the penetration overload signal,and calculate the depth of the simulation penetration,which gains the filter frequency of stress-wave.Meanwhile,we compute the penetration depth on the data of the actual course utilizing the algorithm.The results are close to face.Compared with the traditional numerical simulation and calculation formula,the algorithm has easy-to-use and real-time features.Finally,the design scheme of the algorithm hardware electro-circuit is proposed.
