| 摘 要： | 本文采用有限单元法,运用ANSYS软件对土体在发射器冲击荷载下的变形进行瞬态动力学分析,确定关中某地黄土在受冲击时的位移及应力分布规律。有限元模拟结果与工程实际冲击结果比较吻合,为发射器的后座冲击作用下土的动力性能分析奠定基础,此类研究鲜见发表,从而为发射器进行模态分析和瞬态动力学分析的地基动力参数提供理论依据。

| Abstract: | In this paper, the finite element method is taken and the ANSYS software is used to for transient dynamics analysis of the deformation of soils under emitter impact load to determine the displacement and stress distribution of the loess in Guanzhong under impact. The finite element simulation result is consistent with the practical engineering impact result, which lays foundation for the dynamic performance analysis of soils under emitter impact. Such studies are rarely published, so this paper can provide theoretical basis for the foundation dynamic parameters of emitter modal analysis and transient dynamics analysis. |
