水下目标在水下爆炸作用下的毁伤指标研究

针对某水下目标的抗水下爆炸试验数据，阐明了选用加速度峰值和速度峰值作为测量指标的原因，然后通过相关分析法研究这些指标之间的相关性，利用正交旋转法的因子分析得到影响目标毁伤的公共因子，并通过分析正交旋转因子载荷阵选择出特征指标，讨论特征指标与毁伤模式之间的关系，最后分别利用公共因子数据和特征指标数据进行目标毁伤判别，两组数据的判别结果与实验结果基本一致，证明了特征指标选择的合理性.

Damage indexes of underwater target subjected to underwater explosion

For the experiment data of a underwater target subjected to underwater explosion, the reason of choosing peak acceleration and peak velocity as a measurement was illustrated, and the correlation between these indexes was studied through the relevant analysis method. The common factors affecting the target damage were obtained by using the orthogonal rotating of factor analysis, and the feature indexes were selected through factor loading matrix of orthogonal rotation, and the relationship between feature indexes and damage patterns was discussed. Finally, Results show that the choice of feature indexes is reasonable by distinguishing the target damage by using the common factors and feature indexes.
