摘要
介绍一个实现导弹战斗部威力场数值仿真的集成化软件系统。按照威力场仿真的功能要求,对系统框架和接口进行了设计,给出了战斗部预制破片建模和参数化有限元建模的方法。完成的系统集成了有限元建模、力学仿真和后处理工具。系统能够实现上述工具的协同工作和数据集成,根据数值计算结果计算战斗部破片空间飞散参数和冲击波载荷。仿真实例运行结果表明系统能够满足设计人员的要求。
An integrated software system for numerical simulation of warhead power field simulation was proposed. In accordance with functional requirements of the power field simulation, the system architecture and the interfaces were designed, and preformed fragment and parameterized finite element modeling of the warhead were presented. The finished system integrates several tools of finite element modeling, mechanics simulation, and post-processing. The system enables collaboration of the above-mentioned tools and data integration, and calculates the spatial distribution parameters of the fragments and shock wave load of a warhead based on the numerical simulation results. The simulated results by instance show that the system can satisfy the requirement of designers.
