基于样本库方法的船舶冲击环境预报

Research on shock environment of ship based on sample library method

舰船作为水上作战的主要工具成为国家国防中的重要角色。本文提出一种采用建立样本库的方法研究船舶抗冲击性能。该方法的主要思路是:考虑影响船舶冲击环境的诸多因素,建立3艘不同类型船舶在不同冲击因子作用下的冲击环境样本库。采用样本库方法预报其他船舶冲击环境时无需再进行繁琐、耗时的有限元建模、加载以及数据后处理,实现了冲击环境的快速、便捷预测的功能。

As the important operational tool on water,our country committed to develop ship career, a set of method is put forward to research ship impact resistance performance with the establish of sample library. The mainly ideas of this method is the consideration of various factors, the impact environmental sample libraries of three different types of ship under different impact factors are established based on the above factors research, the impact environment forecast of other ship could directly use the provided impact environmental forecast formula without further tedious, time-consuming finite element modeling, loading and data post-processing, and this realized fast and convenient prediction of the impact environment.
