摘　　要：冲击响应数值模拟在军用与民用领域有广泛的应用需求,但现有串行分析程序难以满足求解规模和效率的需求,因此需要开发并行显式有限元程序。本文在分析了显式有限元串行基本算法的基础上,设计了相应的并行算法,采用模块化程序开发模式基于PANDA程序框架开发了并行显式有限元分析程序DynPack,并进行了算例验证。算例表明,DynPack实现了结构冲击响应的大规模并行计算,并具有较高的并行效率。Numerical simulations of impact response are widely used in military and civil engineering. As the existing serial software can＇t meet the requirements of problem scales and compute efficiency, it is necessary to design the parallel counterpart. The basic algorithms of serial explicit finite element are analyzed, and then the corresponding parallel algorithms are compiled in this paper. And the parallel explicit finite element code DynPack is developed based on the PANDA framework. The two benchmark problems demonstrate DynPack can be used to analyze large scale impact problems, and has a good parallel efficiency.
