中文摘要:球形锥壳是生产破甲弹的关键零部件,关于其成型方法的研究具有重要意义。通过对实际模型的模拟,介绍了数值模拟的一般过程。选择不同的工艺参数,对球形锥壳的挤压成形过程进行了模拟。通过对模拟结果的分析,制定了合适的成形工艺参数。
英文摘要:Spherical cones are key components in producing high explosive anti tank, and the research about its forming methods is very important. The simulation process of spherical cone was introduced by simulating actual model. The extrusion process for spherical cone was simulated by choosing different process parameters. According to the analysis of the results, the appropriate process parameters were defined.
