摘要
低空高速投放弹体能够具有很强的隐蔽性和快速攻击性,但是随之带来了弹体机械结构抗冲击问题。该文针对高速投放入水过程中弹体结构冲击问题进行了仿真研究。首先根据对弹体建立三维实体模型,包括其内部各机械电子以及装药部件的等效配置。然后采用大型流固耦合仿真软件Dytran进行入水冲击过程动态仿真。最后通过分析仿真结果数据得到几点有益的结论,为入水冲击弹体壳体以及内部机构抗冲击设计提供有价值的参考。
High speed and low altitude mining is provided with ulterior and fast characteristics in the assault.Whereas it brings the problem of water entry struture shock.The projectile body water entry procedure is stuied by numerical emulation.At first the three-dimension model is built according to the projectile body structure including mechanism,apparatus and dynamite components the by using famous numerical emulation software dytran the water entry procedure is emulated.Finally the emulation data are analyzed to form some conclusions which provide useful reference for projectile body structure design.
