摘要: 本文通过楔形烟囱模型、在纵向冲击波作用下烟囱断裂位置实验和分析,给出纵向冲击只能产生一道环向断裂,断裂位置与输入冲击波作用周期和烟囱本身固有周期之比有关的结论.

Abstract: Longitudinal shock test and analysis on chimney models are made in this paper. Conclusion is that the fracture location of chimney models is related to the ratio of the shock wave period and chimney inherent period and only one circumferential crack will be produced by longitudinal shock.
