摘要
对由MSC.Dytran仿真计算得到的2种不同初始速度入水弹体入水冲击载荷进行了平稳性检验、功率谱、冲击响应谱、高斯特性、高阶统计等特征分析。研究表明,水雷入水冲击载荷是平稳信号并且为非高斯分布,速度是影响冲击载荷信号的主要因素,为弹体抗冲击总体设计提供依据。
The projectile body water entry impact acceleration is emulated by MSC.Dytran under the different velocity.The data analysis on the impact loading of different characteristics include stationarity check,power spectrum,Gauss character,higher statistic.The impact loading signal was the analysis results provide valuable references to the projectile body＇s shock resistance design of devices
