为分析3维编织复合材料弹道侵彻数值模拟结果的可靠性,采用参数检验和非参数检验2种统计检验方法,对试验与2种数值模拟过程得到的剩余速度分布分别进行了齐一性检验,结果表明:非参数检验方法能准确检验数值模拟结果的可靠性;第2种数值模拟过程得到的剩余速度分布与试验结果分布相同,具有更高的可靠性。
In order to analyze the reliability of numerical simulation results of ballistic penetration of 3-D braided composites, two statistical test methods, parametric test and non-parametric test, were used to test the homogeneity of the residual velocity distribution obtained from the two numerical simulations The results show that the nonparametric test method can accurately test the reliability of the numerical simulation results. The residual velocity distribution obtained in the second numerical simulation process has the same distribution with the test results and has higher reliability.
