摘要
采用有限元模拟方法,对正拱开缝型爆破片爆破压力进行了研究,探讨了爆破压力与预拱高度、孔间桥长之间的关系。正拱开缝爆破片爆破压力与相对预拱高度成线性关系。正拱开缝型爆破片的承载能力主要由桥长来决定。爆破压力跟桥长在数量上成正比。
The rupture pressure of arch slotted bursting disc was studied by using finite element method. The influence of the pre-arch height and the length between the holes on the rupture pressure of arch slotted bursting disc was discussed. The results indicate that, the rupture pressure increases linearly with the increase of the relative pre-arch height; The load carrying capacity of the arch slotted bursting disc is decided mainly by the length between the holes： The rupture pressure of arch slotted bursting disc has a direct ratio with the length between the holes quantitatively.
