doi:10.3969/j.issn.1000-1093.2016.11.005

Abstract

Abstract: In order to predict the damage effect of damage element, the actual test is replaced with a virtual test. Based on the accurate simulation technology of damage elements penetrating into gelatin, the solution of K file of finite element software DYNA is combined with the development of VC++6.0 program in consideration of random variables in practical test, test conditions, test sample size, data processing, test result evaluation and virtual scene. The random variables are added to the solution of K file automatically, and the relative standard deviation formula and damage effectiveness evaluation equation are integrated. The virtual test results are analyzed. A database is built for damage element data, virtual experimental data and the measured data for result comparison. The results show that the multiple virtual test results are distributed in a stable range, and the multiple virtual test results are consistent with the actual test results.

Key words: ordnance science and technology, damage element, gelatin, penetration, virtual test
